Volume Measurement Systems
Metric System
International standard system based on the liter and cubic meter.
- • Milliliters (mL) - Small volumes
- • Liters (L) - Everyday measurements
- • Cubic meters (m³) - Large volumes
- • Used worldwide except US
US Customary System
Volume measurements commonly used in the United States.
- • Fluid ounces (fl oz) - Small volumes
- • Cups, pints, quarts - Medium volumes
- • Gallons (gal) - Large volumes
- • Different from Imperial system
Imperial System
British Imperial measurements, larger than US equivalents.
- • Imperial fluid ounces - Larger than US
- • Imperial pints - 20 fl oz vs US 16 fl oz
- • Imperial gallons - About 20% larger
- • Used in UK and some former colonies
Cooking Measurements
Practical measurements for recipes and food preparation.
- • Teaspoons (tsp) - Small ingredients
- • Tablespoons (tbsp) - Common measure
- • Based on US customary system
- • Essential for recipe conversion

Volume Conversion FAQ
What's the difference between US and Imperial gallons?
US gallons are smaller at 3.785 liters, while Imperial gallons are 4.546 liters. This 20% difference is important for fuel economy comparisons and international trade.
Why are cooking measurements different from standard measurements?
Cooking measurements evolved for practical kitchen use. While a fluid ounce is technically 29.5735 mL, recipes often round to 30 mL for simplicity.
How accurate are the volume conversions?
Our conversions use precise conversion factors and display results to 6 decimal places, providing accuracy suitable for scientific, engineering, and commercial applications.
Which volume units should I use for my project?
Use metric (liters, mL) for scientific work and international projects, US customary for American cooking and commerce, and Imperial for UK-based applications.
