Volume Converter
Pick a 'from' unit, a 'to' unit, and enter a value. The calculator returns the converted result plus equivalents in every metric, US liquid, and cubic unit.
Volume cannot be negative. · e.g. 1
Internal base unit is the liter. US liquid units (tsp, tbsp, fl oz, cup, pint, quart, gallon) differ from imperial; this calculator uses US definitions.
Cup → Milliliter
236.588 ml
1 cup = 236.588 ml
1 L = 1,000 mL = 1,000 cc. 1 US gallon = 3.785 L. 1 ft³ ≈ 28.32 L. 1 yd³ ≈ 764.55 L. US liquid units used; imperial units differ.
Examples
1 cup to mL
≈ 236.588 mL
1 gallon to liters
≈ 3.785 L
1 m³ to ft³
≈ 35.315 ft³
How it works
All units are stored as factors relative to the liter. Convert through the liter base: value times source factor gives liters, then divide by target factor.
Formula · output = value × factor(from) ÷ factor(to)
Notable factors: 1 cup ≈ 0.237 L · 1 fl oz ≈ 29.57 mL · 1 gallon ≈ 3.785 L · 1 ft³ ≈ 28.32 L · 1 m³ = 1,000 L. US liquid measure throughout.

Frequently asked questions
A US gallon is 3.785 liters; an imperial (UK) gallon is 4.546 liters. They are different units that share a name. This calculator uses US liquid measure throughout (US gallon, US pint, etc.). For UK conversion, multiply US values by 1.20095 or look up imperial-specific factors.
Yes, in practice. 1 milliliter equals 1 cubic centimeter exactly. Both equal 1/1000 of a liter. The 'cc' notation is common in medical and engineering contexts; 'mL' is more common in everyday cooking and chemistry.
Useful US measure conversions: 1 tablespoon = 3 teaspoons. 1 cup = 16 tablespoons = 8 fl oz. 1 pint = 2 cups. 1 quart = 2 pints = 4 cups. 1 gallon = 4 quarts = 16 cups = 128 fl oz. The calculator handles all of these directly.
Cubic foot (ft³) and cubic yard (yd³) are common for bulk materials (concrete, gravel, soil, mulch) and HVAC sizing. 1 ft³ ≈ 7.48 US gallons ≈ 28.3 L. 1 yd³ = 27 ft³ ≈ 764.55 L. For practical L × W × H estimation, use the cubic feet or cubic yard calculator.
Yes, US measure has separate liquid and dry pints. A US dry pint is about 16% larger than a US liquid pint. This calculator uses US liquid measure only for the pint/quart/gallon group. For dry-volume work (produce, grain), use a dedicated dry-volume conversion.
Because that's a different question. This is a unit converter. For volume from length × width × height (or sphere/cylinder/cone formulas), use the volume calculator. For specifically cubic feet or cubic yards from dimensions, use those dedicated calculators.
