Volume Unit Converter
Convert volume units for cooking, science, and more.
Volume Unit Converter converts liquid and volumetric measurements between metric units (milliliters, liters, cubic meters) and US customary cooking units (teaspoons, tablespoons, cups, fluid ounces, pints, quarts, gallons) instantly in your browser.
How it works
Liters serve as the base unit. Each unit has an exact factor relative to liters; your input converts to liters first, then to the target unit, so recipe-scale and industrial-scale conversions both stay precise.
Benefits
- Covers metric and US customary cooking and industrial volume units
- Exact factors for teaspoons, tablespoons, and gallons
- Instant live conversion with no submit step
- Fully client-side—your measurements never leave the browser
Use cases
- Scale recipes between metric and US measuring cups or spoons
- Convert vehicle fuel tank or tank capacity specs
- Check lab or industrial volumes in liters and cubic meters
- Translate beverage or container sizes across regions
Best practices
- Confirm recipes use US customary units before converting cups or tsp
- Use milliliters for small precise cooking or lab quantities
- Prefer liters or cubic meters for larger industrial volumes
- Double-check fluid ounces (volume) versus ounces (weight) before converting
Common mistakes
- Confusing fluid ounces (volume) with ounces (weight)
- Assuming UK and US cups or gallons are the same size (they are not)
- Mixing up tablespoons and teaspoons in scaled recipes
- Forgetting that 1 cubic meter is 1,000 liters, not 100

Frequently asked questions
- Which volume units are supported?
- Milliliters, liters, cubic meters, teaspoons, tablespoons, cups, fluid ounces, pints, quarts, and gallons—covering cooking, US customary, and metric measurements.
- Are these US or UK measurements?
- Cups, teaspoons, tablespoons, fluid ounces, pints, quarts, and gallons use US customary definitions (for example 1 US gallon = 3.785411784 liters), the most common convention for recipes online.
- How many teaspoons are in a tablespoon?
- Exactly 3 teaspoons equal 1 tablespoon. The converter uses precise teaspoon and tablespoon factors relative to liters to keep small-quantity conversions accurate.
- Can I convert cooking measurements to milliliters?
- Yes. Set the From unit to cups, tablespoons, or teaspoons and the To unit to milliliters (or liters) for precise metric equivalents.
- Does this tool upload my measurements?
- No. All conversions happen locally in your browser; your values are never sent to ToolHub or any server.
- Why do my liters-to-gallons results differ from other sites?
- Some sites round the gallon factor. This tool uses the exact defined factor of 3.785411784 liters per US gallon for maximum precision.
