How it works
Volume conversion expresses liquid and solid capacity across metric and US customary units, with 1 US gallon equal to 3.78541 liters and 1 US cup equal to 236.588 mL as the most common cooking and everyday references.

Volume unit reference
Every unit here converts through milliliters.
1 tsp = 4.929 mL, 1 Tbsp = 14.787 mL, 1 fl oz = 29.574 mL, 1 cup = 236.588 mL, 1 gal = 3,785.41 mL
The US customary system used here differs from the UK imperial system: a US fluid ounce is 29.5735 mL while a UK fluid ounce is 28.4131 mL, and a US pint is 16 fl oz (473 mL) while a UK pint is 20 fl oz (568 mL). A cubic meter is exactly 1,000 liters by definition, since a liter is a cubic decimeter.
US and UK units share names but not sizes
A recipe or bottle labeled in fluid ounces, cups or pints can mean a noticeably different amount depending on whether it follows the US or UK, imperial, system. When following a recipe from a different country, check which standard it uses rather than assuming it matches your own.
Frequently asked questions
How many liters is a US gallon?
1 US gallon equals 3.78541 liters. To convert gallons to liters, multiply by 3.785. Example: a 15-gallon fuel tank holds about 56.8 liters. Going the other way, divide liters by 3.785. Note that the US gallon differs from the UK, imperial, gallon, which is 4.54609 liters, about 20% larger, so always check which gallon is meant.
How many milliliters are in a cup?
1 US cup equals 236.588 mL, commonly rounded to 237 mL or 240 mL on labels. 1 tablespoon is 14.787 mL, about 15 mL, and 1 teaspoon is 4.929 mL, about 5 mL. So 1 cup equals 16 tablespoons, which equals 48 teaspoons. In the UK, a metric cup is 250 mL, so recipes from different countries can differ slightly.
What is the difference between a US fluid ounce and a UK fluid ounce?
A US fluid ounce is 29.5735 mL, while a UK, imperial, fluid ounce is 28.4131 mL, a difference of about 4%. More importantly, a US pint is 16 fl oz, 473 mL, while a UK pint is 20 fl oz, 568 mL. This means a UK pint of beer is significantly larger than a US pint. Always check which standard a recipe or container uses.
How many tablespoons are in a cup and how does that help in cooking?
There are 16 tablespoons in 1 US cup. Knowing this lets you scale recipes easily: half a cup is 8 tablespoons, a quarter cup is 4 tablespoons. Similarly, 1 tablespoon is 3 teaspoons, so 1 cup is 48 teaspoons. When you do not have a measuring cup, counting tablespoons gives an accurate substitute.
How do I convert cubic meters to liters?
1 cubic meter equals 1,000 liters. This is exact by definition: 1 liter equals 1 cubic decimeter, which is 0.001 cubic meters. To convert cubic meters to liters, multiply by 1,000. Example: a 0.05 cubic meter aquarium holds 50 liters. Going the other way, divide liters by 1,000. This relationship also means 1 kg of water equals 1 liter, which equals 1 cubic decimeter.
