How It Works
This tool converts between metric volume units (ml, liters, cubic meters) and US customary units (cups, pints, gallons, fluid ounces) — commonly needed for both cooking measurements and larger liquid volumes like fuel or paint.
Metric vs. US customary — and the UK difference
US customary volume units (cup, pint, gallon, fluid ounce) are different in size from the same-named UK/Imperial units — a US gallon (3.78541 L) is smaller than an Imperial gallon (4.54609 L). This tool uses US customary definitions, the more commonly referenced standard online and in most recipes.
Examples
Recipe conversion
A recipe calling for 2 cups of liquid: 2 × 236.588 ≈ 473 ml.
Fuel/large volume
A 15-gallon fuel tank: 15 × 3.78541 ≈ 56.78 liters.
Common Use Cases
- Converting recipe measurements between US cups/tablespoons and metric ml
- Converting vehicle fuel tank capacity or paint/liquid quantities between gallons and liters
- Lab or scientific measurements needing ml-to-liter or cubic conversions
Tips
- If you're following a UK recipe or working with UK-specified volumes (like Imperial pints in a pub context), be aware this converter uses US customary definitions — a UK pint (568 ml) is meaningfully larger than a US pint (473 ml).
- For baking specifically, weight-based measurements (grams) are more precise than volume (cups) since ingredient density varies — use the Weight Converter alongside this one if a recipe gives both.
