US Cups to Milliliters Converter
1 US cup = 236.588 milliliters
The us cup and the milliliter are both essential units in volume and capacity measurement. The milliliter equals one cubic centimeter and became essential in medical and pharmaceutical practice for precise liquid measurement. Since 1 cup equals 236.588 mL, understanding this relationship is valuable for anyone working in fuel management or medicine.
Did you know? Did you know? Most coffee mugs hold about 1.5 US cups of liquid. Converting that to milliliters: that is approximately 354.882 milliliters.

About US Cups to Milliliters
The cups-to-milliliters conversion is the most important volume conversion for home cooks, especially when following recipes from different countries. American recipes use cups, while European and most international recipes use milliliters or grams.
Common baking conversions: 1 cup of water = 236.6 mL (and weighs 236.6 grams). 1 cup of all-purpose flour = 236.6 mL by volume but only about 125 grams by weight. 1 cup of sugar = 236.6 mL but about 200 grams. This is why baking by weight (grams) is more accurate than by volume (cups).
Standard recipe measurements convert as: 1/4 cup = 59.1 mL, 1/3 cup = 78.9 mL, 1/2 cup = 118.3 mL, 2/3 cup = 157.7 mL, 3/4 cup = 177.4 mL.
In daily life, a standard coffee mug holds about 1.5 cups (355 mL). A typical soup bowl is 1.5-2 cups (355-473 mL). The recommended daily water intake of 8 cups equals about 1,893 mL or roughly 1.9 liters.
Note that cup sizes vary internationally: a US cup is 236.6 mL, a metric cup (Australia, New Zealand) is 250 mL, a Japanese cup is 200 mL, and a Canadian cup is 227.3 mL (though Canada increasingly uses metric cups of 250 mL).
For quick estimation, 1 cup is roughly 240 mL, and 4 cups make about 1 liter.
Frequently Asked Questions
How many mL is 1 cup?
1 US cup equals 236.588 mL. A metric cup (used in Australia) is 250 mL. Always check which cup measurement a recipe uses.
How many cups in a liter?
There are approximately 4.227 US cups in 1 liter. For practical purposes, 4 cups is close to 1 liter (946.4 mL).
Is a coffee mug the same as a measuring cup?
No. A standard US measuring cup is 236.6 mL (8 fl oz), while most coffee mugs hold 300-400 mL (10-14 fl oz). Always use a proper measuring cup for recipes.
How do I convert cups to grams for baking?
It depends on the ingredient. 1 cup of water = 236.6 g, but 1 cup of flour = ~125 g, and 1 cup of sugar = ~200 g. Use a weight conversion chart specific to each ingredient for accuracy.
