About Volume Conversion

Volume is a measure of the amount of three-dimensional space occupied by a substance, container, or object. It's commonly used in cooking, chemistry, engineering, and everyday life. Different countries and industries use different volume measurement systems.

Metric Units

  • Milliliter (mL): Small volumes, medicine, cooking (1 mL = 1 cm³)
  • Liter (L): Beverages, containers, fuel (1 L = 1,000 mL)
  • Cubic Meter (m³): Large volumes, shipping, construction (1 m³ = 1,000 L)

Imperial Units

  • Teaspoon/Tablespoon: Cooking measurements, medicine
  • Fluid Ounce (fl oz): Beverages, cosmetics (1 fl oz ≈ 30 mL)
  • Cup: Cooking, baking (1 cup = 8 fl oz = 237 mL)
  • Pint (pt): Beverages, milk (1 pt = 2 cups = 473 mL)
  • Quart (qt): Larger containers (1 qt = 2 pt = 946 mL)
  • Gallon (gal): Fuel, large containers (1 gal = 4 qt = 3.785 L)
  • Cubic Foot (ft³): Large volumes (1 ft³ = 28.317 L)

US vs UK Gallons

Note: This converter uses US gallons. UK (Imperial) gallons are larger:

1 tbsp = 3 tsp

Volume Scaling

Volume = L × W × H

If dimensions double, volume increases 8×

Frequently Asked Questions

How many liters are in a gallon?

1 US gallon equals 3.785 liters. For UK (Imperial) gallons, 1 gallon equals 4.546 liters.

What's the difference between ml and L?

Milliliter (mL) and liter (L) are both metric volume units. 1 liter = 1,000 milliliters. mL is used for small amounts, L for larger volumes.

How many cups in a liter?

1 liter equals approximately 4.23 cups (US). This is useful for converting cooking recipes.

Is a fluid ounce the same as an ounce?

No. A fluid ounce (fl oz) measures volume, while an ounce (oz) measures weight. 1 fl oz = 30 mL, but the weight varies by substance.

Why do volume units cube when converting?

Because volume is three-dimensional, you must cube the conversion factor. For example: 1 m = 3.28 ft, so 1 m³ = (3.28)³ = 35.31 ft³.
