How to use the volume unit calculator
Convert between litres, gallons, cups and cubic metres. Enter volume in the field above; the us gallons, us cups, fluid ounces, cubic metres, millilitres are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- L — Volume (L)
Worked example
With volume = 10 L, the calculator gives us gallons ≈ 2.64172 gal; us cups ≈ 42.2675 cup; fluid ounces ≈ 338.14 fl oz; cubic metres ≈ 0.01 m³; millilitres ≈ 10,000 mL.
Frequently asked questions
What is the formula for the volume unit calculation?
US gallons (gal) = L × 0.264172. US cups (cup) = L × 4.22675. Fluid ounces (fl oz) = L × 33.814. Cubic metres (m³) = L / 1000. Millilitres (mL) = L × 1000. Here L is volume (L).
What inputs do I need for the volume unit converter calculator?
You need volume in L. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
