In-depth guide
Convert between twelve volume units — millilitres, litres and cubic metres on the metric side; teaspoons, tablespoons, cups, fluid ounces, pints, quarts and gallons (US customary) on the recipe side; plus cubic inches and cubic feet for engineering.

This converter uses US customary measures for tsp / tbsp / cup / fl oz / pt / qt / gal. The Imperial counterparts share the same names but are different sizes:
If you specifically need Imperial volumes, multiply litres by 0.21997 for UK gallons or by 35.195 for UK fl oz.
Use this converter when you need a quick value across metric, imperial, data, time, or other unit systems. Use domain-specific engineering, lab, or compliance software when tolerances, significant figures, or standards must be formally controlled.
Browser-first by design. The tool page explains any exception before you use it.
Your conversion values stay in the browser and update locally as you type. EpitomeTool does not upload source values, copied results, or unit choices to a server.
The US liquid gallon: 1 gal = 3.785411784 litres exactly. This is the most-requested unit for North American recipes, fuel and beverages. The UK Imperial gallon is about 20% larger (1 UK gal ≈ 4.54609 L); if you need it specifically, multiply litres by 0.21997 instead.
US customary. 1 tsp = 4.929 mL, 1 tbsp = 14.787 mL, 1 cup = 236.59 mL, 1 fl oz = 29.574 mL. Australian metric cups (250 mL) and UK Imperial cups (284 mL) are different — convert via mL if you're not sure.
Yes. 1 cm³ = 1 mL exactly by SI definition since 1964. The unit isn't listed separately because it's interchangeable with mL; type a value as mL and read it as cm³.
Just over 33.81 US fluid ounces. A 500 mL water bottle is ≈ 16.9 fl oz, hence the common '16.9 oz' bottle size you see on US shelves.
Not supported — barrel definitions vary by industry (oil = 42 US gal, beer barrel = 31 US gal, wine barrel = 31.5 US gal). The supported list covers everyday cooking, science and commerce. For specialty conversions, multiply through litres manually.
