Volume Converter
Last updated: June 19, 2026
A volume converter is a measurement utility that translates three-dimensional capacity and volume values between different metric and imperial systems. The calculator supports conversions between metric units (including milliliters, liters, and cubic meters) and US or UK imperial units (including teaspoons, tablespoons, fluid ounces, cups, pints, quarts, gallons, and cubic feet). It applies standard conversion factors to guarantee precision. Cooks, shippers, science students, and manufacturers use this tool to standardize capacity measurements across different standards.
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.
Quick Answer
Convert capacity and volume values between metric and imperial units. Enter your value and select units for quick conversions across liters, gallons, cups, and ounces.
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.
