Volume Conversions

Volume conversions are used every day in cooking, bartending, medicine, and fuel measurement. The US uses customary units (gallons, quarts, cups, fluid ounces) while most of the world uses metric (liters, milliliters). A key complication: US fluid ounces and UK fluid ounces differ, as do US and UK gallons. Precise conversion is essential for recipes, drug dosing, and international trade.

  • ✓Converting cups and tablespoons in US recipes to metric measurements
  • ✓Converting liters to gallons for fuel calculations and tank sizing
  • ✓Converting mL to fl oz for medicine dosing and beverage labeling
  • ✓Converting cubic feet to liters for aquariums and water storage tanks

Frequently Asked Questions — Volume

How many cups are in a liter?
1 liter equals approximately 4.227 US cups. A US cup equals 236.6 mL, so divide any mL value by 236.6 to get cups. One liter is also approximately 2.113 US pints or 1.057 US quarts.
How many milliliters are in a fluid ounce?
1 US fluid ounce equals 29.5735 mL. To convert fl oz to mL, multiply by 29.5735. Note: a UK fluid ounce equals 28.4131 mL, slightly less than the US version.
What is the difference between a US gallon and a UK gallon?
A US gallon equals 3.785 liters (128 US fl oz), while a UK imperial gallon equals 4.546 liters (160 UK fl oz) — about 20% larger. This difference is important for fuel economy comparisons and international recipe scaling.
