Volume Converter
Convert between different volume units including metric (liters, cubic meters), imperial/US (gallons, cubic feet), and cooking measurements (cups, tablespoons).
Note: US and UK liquid measures differ slightly. For example, a US gallon is about 3.785 liters, while a UK (imperial) gallon is about 4.546 liters. This converter uses the specified standard for each unit.
Conversion Formula:
Common Volume Conversions
1 liter = 1000 milliliters
1 US gallon = 3.78541 liters
1 UK gallon = 4.54609 liters
1 cubic meter = 1000 liters
1 US cup = 236.588 milliliters
1 cubic foot = 28.3168 liters
Practical Applications
Cooking and Baking
Converting between different measurement systems in recipes, especially when using cookbooks from different countries.
Fuel Consumption
Converting between gallons and liters for fuel purchases and consumption calculations when traveling internationally.
Water Usage
Calculating water consumption for household use, swimming pools, or irrigation systems using different volume units.
Shipping and Storage
Determining container volumes and capacities for shipping, storage, or transportation needs.
US vs UK Liquid Measurements
The United States and the United Kingdom use different definitions for some common volume measurements:
| Measurement | US System | UK/Imperial System | Difference |
|---|---|---|---|
| Fluid Ounce | 29.5735 ml | 28.4131 ml | ~4% larger in US |
| Cup | 236.588 ml | 284.131 ml | ~20% larger in UK |
| Pint | 473.176 ml | 568.261 ml | ~20% larger in UK |
| Quart | 946.353 ml | 1136.52 ml | ~20% larger in UK |
| Gallon | 3.78541 L | 4.54609 L | ~20% larger in UK |
Tip: When following recipes, pay attention to whether they use US or UK/Imperial measurements, especially for baking where precision matters.
Volume Calculation Tips
For Rectangular Containers
Volume = Length × Width × Height
Example: A box measuring 2 m × 3 m × 4 m has a volume of 24 cubic meters (m³).
For Cylindrical Containers
Volume = π × radius² × height
Example: A cylinder with radius 2 m and height 5 m has a volume of approximately 62.83 cubic meters (m³).
For Spherical Containers
Volume = (4/3) × π × radius³
Example: A sphere with radius 3 m has a volume of approximately 113.1 cubic meters (m³).
