Formula
cubic meters = value x unit factor (1 US gal = 231 in3 = 0.003785411784 m3 exactly; 1 UK gal = 4.54609 L)Understanding Volume Conversion
Volume units come in two families that share names: US customary (gallon, quart, pint, cup, fluid ounce) and British imperial (the same names with different sizes). The US gallon is defined as exactly 231 cubic inches, or 3.785411784 liters. The imperial gallon is exactly 4.54609 liters, about 20 percent larger. Cooking measures such as teaspoons and tablespoons are derived from the US gallon here.
Tips and Best Practices
- 1A US gallon is about 3.785 liters; an imperial gallon is about 4.546 liters. Check which one a recipe or fuel figure means.
- 2One US cup is about 236.6 mL, though nutrition labels round a cup to 240 mL.
- 3For liquids in cooking, 3 teaspoons make 1 tablespoon and 16 tablespoons make 1 US cup.
Real-World Example
3 US gallons is 3 x 3.785411784 = 11.356 liters. A 2 liter bottle holds 2 / 0.2365882365 = 8.45 US cups.
Common Mistakes to Avoid
- Using US gallons for a UK recipe or car fuel figure, which can be off by about 20 percent.
- Assuming a fluid ounce and an ounce of weight are the same; they measure different things.
- Mixing the US pint (473 mL) with the imperial pint (568 mL).
