Formula
All volume conversions use milliliters as an intermediate base unit. The input is first converted to milliliters, then from milliliters to the target unit using standard US customary and metric conversion factors.
Unit conversion note
Conversion calculators use standard metric, imperial, and US customary relationships.
Cooking and regional units may vary, so check the unit system shown on the calculator before relying on a result.

Common Examples
Understanding the Concept
Volume conversion is a daily necessity in cooking, baking, science, and many other fields. Whether you are scaling a recipe that uses cups and tablespoons, working with metric liters and milliliters in a laboratory, or comparing fuel quantities in gallons and liters, this converter handles all the common volume units with precise conversion factors based on US customary measurements.
Volume Units Explained
The units in this converter fall into two main systems:
Metric Units:
- Milliliter (ml): One thousandth of a liter. Common in medicine and science.
- Liter (L): The standard metric unit of volume. One liter equals 1,000 ml or about 33.8 fluid ounces.
US Customary Units:
- Gallon: 128 fl oz, commonly used for large liquid quantities.
- Quart: One quarter of a gallon (32 fl oz).
- Pint: Half a quart (16 fl oz).
- Cup: Half a pint (8 fl oz). The standard cooking measurement.
- Fluid Ounce (fl oz): A small volume unit, about 29.6 ml.
- Tablespoon (tbsp): Half a fluid ounce (3 teaspoons).
- Teaspoon (tsp): The smallest common cooking measure, about 4.93 ml.
US Customary Volume Relationships
Understanding the relationships between US customary volume units makes conversion easier:
- 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fl oz
- 1 quart = 2 pints = 4 cups = 32 fl oz
- 1 pint = 2 cups = 16 fl oz
- 1 cup = 8 fl oz = 16 tbsp = 48 tsp
- 1 fl oz = 2 tbsp = 6 tsp
- 1 tbsp = 3 tsp
Cooking Conversion Tips
When converting volumes for cooking and baking, keep these tips in mind:
- For dry ingredients like flour, weight-based measurements (grams) are more accurate than volume, since packing density varies.
- US cups and UK cups are slightly different. A US cup is 236.6 ml, while an Imperial cup is 284.1 ml. This converter uses US measurements.
- Australian tablespoons are 20 ml, while US tablespoons are about 14.8 ml.
- When precision matters in baking, use a kitchen scale rather than volume measures for dry ingredients.
