Cubic Meter to Gallon (US) (m³ to US gal)
Result
264.1720524 Gallon (US)
Formula
US gal = m³ × 264.1720524
1 m³ = 264.1720524 US gal, and 1 US gal = 0.003785411784 m³.
The litre is exactly 1 dm³ (0.001 m³). The US gallon is defined as 231 cubic inches, which makes it exactly 3.785411784 L; quarts, pints, cups and fluid ounces are fixed fractions of it.
Worked examples
- 1 m³ × 264.1720524 = 264.17205 US gal
- 10 m³ × 264.1720524 = 2,641.7205 US gal
- 100 m³ × 264.1720524 = 26,417.205 US gal
Common mistakes
- US and UK (imperial) measures share names but not sizes: the imperial gallon is 4.54609 L (20% larger), the imperial pint 568 mL and the imperial fluid ounce 28.41 mL.
- This converter uses US customary volumes. A US cup is 236.59 mL, a metric cup 250 mL, and US nutrition labels round a cup to 240 mL.
- US dry measures (dry pint, bushel) are a separate system and are not the same as liquid pints.
