About Volume conversions
Volume conversions are used daily in cooking, chemistry, medicine, and fuel measurement. The US system uses fluid ounces, cups, pints, quarts, and gallons — while the metric system works with milliliters and liters. Mixing up these systems in a recipe can produce seriously wrong results.
In cooking, US recipes use cups and tablespoons while European and Australian recipes use milliliters and grams. Key cooking conversions: 1 cup = 236.6 mL, 1 tablespoon = 14.79 mL, 1 teaspoon = 4.93 mL. When buying beverages internationally, a standard 1-liter bottle holds 33.8 fluid ounces — slightly more than a US quart (32 oz). Medicines are always measured metrically: liquid doses in mL, IV bags in liters.
For fuel economy comparisons between US and international cars, volume conversion is essential. 1 US gallon = 3.785 liters. Note that the US gallon and UK imperial gallon are different — the UK gallon is about 20% larger at 4.546 liters, so fuel prices per gallon cannot be directly compared.
Frequently asked questions
How many milliliters are in a cup?▾
One US cup equals 236.588 milliliters (approximately 237 mL). There are 8 fluid ounces in a cup, and 1 fluid ounce = 29.574 mL. Note: an Australian or Canadian "metric cup" is exactly 250 mL, slightly larger than the US cup.
How many liters is a gallon?▾
One US liquid gallon equals 3.785 liters. The UK imperial gallon is larger at 4.546 liters. To convert US gallons to liters, multiply by 3.785. A 5-gallon water jug = 18.9 liters.
How do I convert fluid ounces to milliliters?▾
Multiply fluid ounces by 29.574 to get milliliters. Quick reference: 1 oz ≈ 30 mL, 8 oz = 237 mL (1 cup), 16 oz = 473 mL (1 pint), 32 oz = 946 mL (1 quart). Reverse: multiply mL by 0.0338 to get fluid ounces.
