Which Cup Does My Recipe Use?

Recipes from US websites and cookbooks use the 236.6 ml cup. Recipes from Australia and New Zealand use the 250 ml cup, and newer Canadian recipes do too. The gap is 13.4 ml per cup, which is about 1 tablespoon. That barely matters for 1 cup, but across 4 cups it adds up to 54 ml.

ML to Cups Chart

To change ml to cups, divide by 236.6 for a US cup or by 250 for a metric cup. The kitchen measure column turns the answer into cups and tablespoons you can actually pour. One US cup holds 16 tablespoons, so each tablespoon is about 14.8 ml.

50 ml	0.21	3 tbsp	0.20

Common Bottle and Can Sizes in Cups

A 473 ml bottle holds 16 US fluid ounces, which is exactly 2 cups. A 355 ml soda can holds 1 1/2 cups. A 500 ml water bottle is 2 cups plus 2 tablespoons, and a 750 ml wine bottle is 3 cups plus 3 tablespoons. A 1 liter carton holds about 4 1/4 US cups.

How to Convert Cups to ML and ML to Cups

You only need one number: 236.6 ml in each US cup. Multiply cups by 236.6 to get ml, or divide ml by 236.6 to get cups. For a metric cup, use 250 instead.

Cups to ML

Multiply the cups by 236.6. For 1 1/2 cups, 1.5 × 236.6 = 354.9, so the answer is 355 ml. In a metric cup, 1 1/2 cups is 1.5 × 250 = 375 ml.

ML to Cups

Divide the ml by 236.6. For 300 ml, 300 ÷ 236.6 = 1.27 cups. The leftover 0.02 cup is less than half a tablespoon, so measure 1 1/4 cups.

Cups, Spoons and Fluid Ounces

One US cup holds 8 fluid ounces, 16 tablespoons or 48 teaspoons. The table shows each one in ml, with the rounded values the FDA uses on food labels. Use the exact column for cooking and the label column to read a package.

Unit	Exact ml (NIST)	Label ml (FDA)
1 cup	236.6 ml	240 ml
1 fluid ounce	29.6 ml	30 ml
1 tablespoon	14.8 ml	15 ml
1 teaspoon	4.9 ml	5 ml

An Australian tablespoon holds 20 ml, not 15 ml. That is a third more liquid in every spoon. If an Australian recipe lists tablespoons, use 4 US teaspoons for each one.

Tips for Measuring Liquids by the Cup

Liquids are the easiest thing to measure by volume, but a few habits keep your numbers close. These tips match the values on this page. Each one fixes a common mistake.

Use a liquid measuring cup. A clear cup with a spout and printed ml lines is made for liquids. A dry cup must be filled to the brim, so liquid spills before you reach the top.
Read at eye level. Set the cup on a flat counter and bend down to check the line. Looking from above makes the liquid look higher than it is.
Check the recipe’s country. A US recipe uses 236.6 ml cups, while an Australian recipe uses 250 ml cups.
Weigh water when it matters. One ml of water weighs about 1 gram, so 1 US cup of water weighs about 237 grams.
Do not use ml for dry ingredients. One cup of flour takes up 237 ml but weighs only 120 grams. For flour, sugar or butter, use the cups to grams converter.
