Convert cubic meters, liters, milliliters, cubic centimeters, cubic feet, cubic inches, or cubic yards to US or Imperial gallons.
Assumptions Assumptions
- Conversions are volume-to-volume only; no density or temperature corrections.
- Results are rounded to 6 decimal places in the calculator for readability.
- Unit standards used: 1 m³ = 1000 L; 1 US gal = 3.785411784 L; 1 Imperial gal = 4.54609 L.
- Additional base factors: 1 ft³ = 28.316846592 L; 1 in³ = 0.016387064 L; 1 yd³ = 764.554857984 L; 1 mL = 1 cm³ = 0.001 L.
- US and Imperial (UK) gallons are different—choose the correct gallon type for your use case.
When to Use This Calculator
- Freight and logistics: convert shipment CBM to gallons for liquid cargo planning.
- Tank sizing for water, fuel, and chemicals (aquariums, pools, storage tanks).
- Engineering and construction: convert cubic units (ft³, in³, yd³, m³) to gallons for capacity checks.
Input Definitions
- Cubic Volume — enter value in m³ (CBM), liters, mL, cm³, ft³, in³, or yd³.
- Gallons — choose US gallons or Imperial (UK) gallons.
- Conversions — US: gal = m³ × 264.172052; m³ = gal × 0.003785411784. Imperial: gal = m³ × 219.969248; m³ = gal × 0.00454609.

Example Problem
Convert 3.2 m³ to US gallons.
Use the US formula: US gal = CBM × 264.172052.
US gal = 3.2 × 264.172052 = 845.350568 US gal
