About Millilitres and Gallons

Millilitres (mL) and gallons are units of volume used for measuring liquids. The millilitre is a metric unit, while the gallon is used in the US customary and imperial systems.

Types of Gallons
Gallon Type Millilitres (mL) Litres (L) Cubic Inches
US Liquid Gallon 3,785.41 mL 3.78541 L 231 in³
US Dry Gallon 4,404.88 mL 4.40488 L 268.8025 in³
UK Imperial Gallon 4,546.09 mL 4.54609 L 277.42 in³
Conversion Relationships
  • US Liquid System: 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces
  • UK Imperial System: 1 gallon = 4 quarts = 8 pints = 16 cups = 160 fluid ounces
  • Metric System: 1 litre = 1,000 millilitres = 0.264172 US liquid gallons = 0.219969 UK imperial gallons
Common Uses

These volume measurements are commonly used in:

  • Fuel measurement (petrol, diesel)
  • Water and liquid consumption
  • Food and beverage containers
  • Chemical and pharmaceutical measurements
  • Cooking and recipes (especially when converting between metric and US/UK recipes)
Historical Context

The gallon has evolved over centuries with different definitions in different regions. The millilitre was introduced as part of the metric system during the French Revolution. Today, the metric system (millilitres, litres) is used officially in most countries, though the US still primarily uses gallons for many everyday applications like petrol.
