Why “how much does 1 cup weigh” isn’t the right question to ask
“How much does 1 cup weigh?” is a question that I get asked a lot, but it’s a question that is too vague for me to answer without more details: the reality is that the weight of 1 cup of anything is dependant on the density of the ingredient you are measuring. So 1 cup of all purpose flour does not weigh the same thing as 1 cup of chocolate or 1 cup of skim milk, for example. The volume of 1 cup of flour and 1 cup of milk is the same. Yes. But the weight of 1 cup of these ingredients is not. If you are wondering how to convert from volumes to weights, or vice versa, keep reading or sign up to download this baking conversions chart pdf.
Kitchen tools you need for measuring ingredients
Remember that when you measure out dry ingredients, use cup measures designed for dry ingredients (like these on Amazon), like flour, sugars, oats, etc. On the other hand, use a measuring cup designed for liquids (like this one on Amazon) when you need to measure ingredients like milk, water, and anything that is fluid!
While both tools measure volumes, it’s a lot easier to fill dry measuring cups with dry ingredients and level them by running the back of a knife across. And liquid measuring cups make filling, pouring, and walking around a lot less messy. No spills! Trust me! For nut butters, I use dry measuring cups. Use the tool that you are most comfortable with.
For small quantities of ingredients, never weigh them unless you have a scale that can handle small weights of less than 10 grams. So for ingredients like baking soda, baking powder, and salt, use tablespoons and teaspoons, not your kitchen scale.
If you are unsure, consult this guide to measuring baking ingredients so you use the tools you have properly!
Baking conversions chart
One essential tool if you want to transition to baking with your kitchen scale by weight instead of with measuring cups is a baking ingredients conversion chart. I’ve put together an easy to use Baking Conversions Chart with all the most common baking ingredients that you will need to bake most recipes, including the ones on this blog. The baking conversions chart includes cups, metric & imperial measurements (grams & ounces), and it’s a FREE printable! To get a copy of this free baking conversions chart pdf, click here.
Here are the tools you need to measure ingredients in your kitchen:
- Dry measuring cups: I like heavy duty stainless steel dry measuring cups that sit flat on the counter so that I can spoon ingredients into them easily without the risk of them tipping over. I recommend this OXO set of dry measuring cups from Amazon, which hold together with a magnet.
- Set of measuring spoons: I own this stainless steel set that you can find on Amazon. The spoons fit in most jars.
- Liquid measuring cups: I like this set of glass Pyrex measuring cups that you can find on Amazon. Ideally, you should have a 1 cup liquid measuring cup and a 2 cup liquid measuring cup. I also have a 4 cup measuring cup, which is more useful for cooking than baking (like if you have to measure large cups of stock or water for soups and stews). Oxo makes a set of neat liquid measuring cups that are easy to read from above. If you have trouble bending down to read a cup measurer, I highly recommend the Oxo measuring cups! You can also find them on Amazon.
- Kitchen scale: I have tried several brands but I love the Oxo kitchen scale the most. The OXO kitchen scale takes regular AA batteries, it can also be used to weigh by difference (with negative numbers!), it has a pull out display, and the stainless steel plate that you weigh on can be removed, making washing so much easier—get the OXO kitchen scale on Amazon. By the way, OXO has a new version of their popular kitchen scale on Amazon, but I haven’t tried it yet.
- Technique is everything so make sure to read this guide to measuring ingredients for baking, so that you use the best techniques.
Below you will find a list of baking conversions that I follow when I’m baking so you can easily convert from grams to cups, or the other way around. If you have to replace one ingredient with another in your recipes, make sure to consult this list of baking substitutions to guide you through the process.
Baking conversions for butter from cups to grams
As a rule: 1 stick of butter is 1/2 cup and weighs 115 grams; 2 sticks of butter is 1 cup and weighs 230 grams. A pound of butter is 4 sticks of butter and weighs 450 grams. You should note that 1 stick of butter is also equivalent to 8 tbsp of butter. Half a stick of butter is equivalent to 1/4 cup or 4 tbsp of butter. Don’t confuse the big pound block of butter with the smaller baking sticks.
- 1 cup butter weighs 230 grams
- 3/4 cup butter weighs 173 grams
- 2/3 cup butter weighs 153 grams
- 1/2 cup butter weighs 115 grams
- 1/3 cup butter weighs 77 grams
- 1/4 cup butter weighs 58 grams
Baking conversions for oil from cups to grams
The conversion from volume to weight for oil is slightly different than butter. Oil has a lower density than butter, therefore 1 cup oil weighs a little less than 1 cup of butter. In fact, 1 cup of oil weighs 225 grams.
- 1 cup oil weighs 225 grams
- 3/4 cup oil weighs 170 grams
- 2/3 cup oil weighs 150 grams
- 1/2 cup oil weighs 113 grams
- 1/3 cup oil weighs 75 grams
- 1/4 cup oil weighs 56 grams
The weight of 1 cup of flour varies according to the type of flour. It also varies greatly according to how you fill the measuring cup with flour. I measure flour using the spoon-into-cup method, as opposed to the scooping method. For the spoon-into-cup method, you are spooning the flour into the dry measuring cup. You are not packing and compacting the flour into the cup measure. You are not tapping the measuring cup to pack the flour down so you can squeeze in more! Others may measure flour differently, by the scooping method: if you take your measuring cup and drag it through a bag of flour to fill it, the flour is more compact in the measuring cup and therefore, 1 cup of flour will weigh 140 grams, if not more. If you spoon flour into your measuring cup, 1 cup of flour is equivalent to 125 grams, on average. That’s the way I fill a measuring cup and so that is the conversion I use on Kitchen Heals Soul. Here are some useful conversions of cups to grams of flour.
Baking conversions for all-purpose from cups to grams
As a rule, if you fill your measuring cup by spooning in dry ingredients into the cup, then levelling the top, 1 cup of all-purpose flour weighs 125 grams.
- 1 cup all-purpose flour weighs 125 grams
- 3/4 cup all-purpose flour weighs 94 grams
- 2/3 cup all-purpose flour weighs 83 grams
- 1/2 cup all-purpose flour weighs 63 grams
- 1/3 cup all-purpose flour weighs 42 grams
- 1/4 cup all-purpose flour weighs 31 grams
- NOTE: The above conversions also apply to whole wheat flour, buckwheat flour, bread flour, graham flour, and coconut flour,
Baking conversions for cake flour from cups to grams
Cake flour is lighter than all-purpose flour, and so, 1 cup of cake flour weighs 115 grams. For chestnut flour, 1 cup weighs 115 grams as well. This conversion also applies to chopped nuts: 1 cup of chopped nuts weighs 115 grams.
- 1 cup cake flour weighs 115 grams
- 3/4 cup cake flour weighs 86 grams
- 2/3 cup cake flour nuts weighs 77 grams
- 1/2 cup cake flour weighs 58 grams
- 1/3 cup cake flour weighs 38 grams
- 1/4 cup cake flour weighs 29 grams
- NOTE: The above conversions also apply to chestnut flour and chopped nuts
Baking conversions for granulated sugar & brown sugar (not packed) from cups to grams
Please note that I do not pack my brown sugar into the cup measurer. I spoon the sugar into the measurer. As a rule, 1 cup of sugar weighs 200 grams. If you are measuring brown sugar and you pack the brown sugar tightly into the cup measure, 1 cup of brown sugar will weigh 220 grams, if not more.
- 1 cup granulated or brown sugar weighs 200 grams
- 3/4 cup granulated or brown sugar weighs 150 grams
- 2/3 cup granulated or brown sugar weighs 133 grams
- 1/2 cup granulated or brown sugar weighs 100 grams
- 1/3 cup granulated or brown sugar weighs 67 grams
- 1/4 cup granulated or brown sugar weighs 50 grams
Remember 1 cup of packed brown sugar weighs 220 grams.
Baking conversions for icing sugar from cups to grams
I measure icing sugar (also known as powdered sugar) the same way I measure flour, using the spoon-into-cup method, as opposed to the scoop-into-cup method. This means that you are not packing and compacting sugar into the cup measure. Others may measure icing sugar differently, but this is how I measure mine. Generally, 1 cup of icing sugar weighs 125 grams.
- 1 cup icing sugar or powdered sugar weighs 125 grams
- 3/4 cup icing sugar or powdered sugar weighs 94 grams

- 1/3 cup icing sugar or powdered sugar weighs 42 grams
- 1/4 cup icing sugar or powdered sugar weighs 31 grams
Baking conversions for honey and maple syrup from cups to grams
Honey and maple syrup are quite dense and therefore 1 cup of honey or maple syrup usually weighs 340 grams (12 oz).

- 1/3 cup honey or 1 cup maple syrup weighs 113 grams
- 1/4 cup honey or 1 cup maple syrup weighs 85 grams
Baking conversions for cocoa powder from cups to grams
I measure cocoa the same way I measure flour, using the spoon-into-cup method, as opposed to the scoop-into-cup method. This means that you are not packing and compacting cocoa into the cup measure. Others may measure cocoa powder differently, but this is how I measure mine. In this way, 1 cup of cocoa powder weighs 100 grams.
- 1 cup cocoa powder weighs 90 grams
- 3/4 cup cocoa powder weighs 68 grams
- 2/3 cup cocoa powder weighs 60 grams

Converting metric volumes (mL) to imperial volumes (cups)
Some websites set 1 cup as 236 mL (or 240 mL). Others set 1 cup as 230 mL. Personally, I set 1 cup to 250 mL. The important thing is to be consistent. I’m honestly not sure any measuring cups are truly able to distinguish between 240 mL and 250 mL, so let’s call 1 cup 250 mL and stick with that. Also, I use American tablespoons and teaspoons to measure smaller amounts of ingredients. And 1 tbsp (15 mL) is equivalent to 3 tsp (3 x 5 mL).
- Conversions for US cups to millilitres
- 1 cup = 250 mL
- 3/4 cup = 190 mL
- 2/3 cup = 170 mL
- 1/2 cup = 125 mL
- 1/3 cup = 80 mL
- 1/4 cup = 60 mL
- Conversions for US tablespoons & teaspoons to millilitres
- 1 tbsp = 15 mL
- 1 tsp = 5 mL
- 3/4 tsp = 3.75 mL (rounded to 4 mL)
- 1/2 tsp = 2.5 mL (rounded to 3 mL)
- 1/4 tsp = 1.25 mL (rounded to 1 mL)
- 1/8 tsp = 0.625 mL (rounded to <1 mL)
Please don’t use the mL button on your kitchen scale, if it has one, to measure a volume. Yes, you can weigh a volume, but the button on your kitchen scale is assuming that you are weighing out water, which has a density of 1 gram per millilitre. For example, most oils have a density of 0.9 g per mL, so if you use the mL button on your kitchen scale to measure a volume, it will do so incorrectly and this may lead to problems in your recipe. If you need to measure a volume, use liquid measuring cups (like this set on Amazon).
