Volume Converter
A free volume converter that instantly converts between liters, milliliters, gallons, cups, pints, and quarts.
How volume conversion works
Every conversion uses precise standard factors (e.g., 1 US gallon = 3.78541 liters) — enter a value in any unit and every other unit updates instantly.
Metric vs. US volume units
Liters and milliliters are metric units used worldwide; gallons, cups, pints, and quarts are standard in the US. This converter bridges both systems.
Common Mistakes to Avoid
Confusing US and UK (imperial) gallons
Solution:
A US gallon (3.78541 L) is smaller than a UK imperial gallon (4.54609 L) — this converter uses US units by default; double-check which system a recipe or spec uses.
Mixing up cups, pints, and quarts
Solution:
2 cups = 1 pint, 2 pints = 1 quart — easy to misremember when scaling a recipe.
Confusing volume with weight
Solution:
A cup of flour and a cup of water don't weigh the same — volume converters don't account for ingredient density.
