Quick Reference:
1 L = 1,000 mL = 33.814 US fl oz
1 US gal = 3.785 L = 128 US fl oz
1 UK gal = 4.546 L = 160 UK fl oz
1 m³ = 1,000 L = 264.172 US gal

Volume conversion is essential for cooking, chemistry, construction, and everyday measurements. This converter helps you convert between metric (liters, milliliters) and imperial (gallons, cups, fluid ounces) volume units, as well as cubic units for larger measurements.

Understanding Volume Units

Common volume units and relationships:

  • Metric System: Milliliters (mL), liters (L), cubic centimeters (cm³), cubic meters (m³) - used worldwide
  • US Imperial: Fluid ounces (fl oz), cups, pints, quarts, gallons - used in the US
  • UK Imperial: UK fluid ounces, UK pints, UK quarts, UK gallons - used in the UK (slightly larger than US)
  • Cubic Units: Cubic inches, cubic feet, cubic yards - used for large volumes in construction
  • SI Unit: Cubic meter (m³) is the standard unit, but liter (L) is commonly used for smaller volumes

Common Volume Conversions

Metric Units:
1 L = 1,000 mL = 1,000 cm³
1 m³ = 1,000 L = 1,000,000 mL
1 L = 0.001 m³
1 mL = 0.001 L
US Imperial:
1 US gal = 4 qt = 8 pt = 16 cups
1 US cup = 8 US fl oz
1 US gal = 3.785 L
1 US fl oz = 29.574 mL

US vs UK Imperial Units

Important differences:

  • US Gallon: 3.78541 liters = 128 US fluid ounces. Used in the United States.
  • UK Gallon: 4.54609 liters = 160 UK fluid ounces. Used in the United Kingdom. About 20% larger than US gallon.
  • US vs UK Fluid Ounces: 1 US fl oz = 29.5735 mL, 1 UK fl oz = 28.4131 mL. US fluid ounces are slightly larger.
  • US vs UK Pints: 1 US pint = 0.473 L, 1 UK pint = 0.568 L. UK pints are larger.
  • Always Specify: When converting, always specify whether you're using US or UK imperial units.

Applications of Volume Conversion

Cooking & Baking:
• Recipe conversions
• Liquid measurements
• Ingredient volumes
• Serving sizes
Science & Industry:
• Chemistry measurements
• Construction volumes
• Tank capacities
• Fluid storage

Note: All conversions are mathematically exact based on standard conversion factors. The liter is defined as exactly 1 cubic decimeter (1 dm³) or 0.001 cubic meters. US and UK imperial units differ significantly - always specify which system you're using. For cooking, US measurements are standard in the US, while UK measurements are used in the UK and Commonwealth countries.
