Formulas
base m³ = input × factor of the source unitoutput = base m³ ÷ factor of the target unit1 L = 0.001 m³, 1 US gal = 3.785411784 L, 1 UK gal = 4.54609 L
Quick reference
- 1 liter = 1,000 milliliters
- 1 US gallon ≈ 3.78541 liters
- 1 US cup = 236.588 milliliters
- 1 UK gallon ≈ 4.54609 liters
Calculation logic
All volumes are converted to cubic meters, then to the target unit. Kitchen units use US customary definitions unless labeled UK, so a US cup is not treated as a UK cup.
US and UK gallon/cup definitions differ. This tool labels US and UK units separately where needed.
