Formula
Converted Value = Input Value × (Source Unit in mL) ÷ (Target Unit in mL)How to Convert Volume Units
Volume conversion works by translating your input to milliliters (the base metric unit), then converting to any target unit. This converter supports all common US cooking and metric volume measurements, making it perfect for recipes, beverages, and liquid calculations.
US Cooking Volume Units
- Teaspoon (tsp) — about 4.93 mL. Used for small amounts of spices, extracts, and medicines.
- Tablespoon (tbsp) — about 14.79 mL. Equal to 3 teaspoons. Common for oils, sauces, and dressings.
- Fluid Ounce (fl oz) — about 29.57 mL. Equal to 2 tablespoons.
- Cup — about 236.59 mL. The most common cooking measurement in US recipes.
- Pint — about 473.18 mL. Equal to 2 cups.
- Quart — about 946.35 mL. Equal to 4 cups or 2 pints.
- Gallon — about 3,785.41 mL. Equal to 16 cups or 4 quarts.
Metric Volume Units
Milliliters (mL) and Liters (L) are the standard metric volume units. One liter equals 1,000 mL and is roughly equal to a quart (actually 1.057 quarts). Most of the world uses metric for cooking, science, and everyday measurements.
Quick Volume Conversions for Cooking
- 1 cup ≈ 237 mL (close enough to 250 mL for most recipes)
- 1 liter ≈ 4.2 cups
- 1 gallon ≈ 3.79 liters
- A standard water bottle is 500 mL (about 2.1 cups)
When converting recipes between US and metric, remember that measuring by weight (grams) is more accurate than volume for dry ingredients like flour and sugar. For liquids, this converter gives you precise results.
Frequently Asked Questions
How many cups are in a gallon?
There are 16 cups in a US gallon. The breakdown: 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces = 3,785 milliliters.
How do I convert milliliters to cups?
Divide milliliters by 236.588 to get cups. For example, 500 mL ÷ 236.588 ≈ 2.11 cups. A quick shortcut: 250 mL is almost exactly 1 cup.
What is the difference between fluid ounces and ounces?
Fluid ounces measure volume (liquid capacity), while ounces measure weight. They're not interchangeable — 1 fluid ounce of water weighs about 1.04 ounces, but 1 fluid ounce of honey weighs about 1.5 ounces due to its higher density.
How many tablespoons are in a cup?
There are 16 tablespoons in 1 cup. Other useful measurements: 1 tablespoon = 3 teaspoons = 0.5 fluid ounces = about 14.8 mL.
What is the difference between US and Imperial gallons?
A US gallon is 3,785 mL (128 fl oz), while an Imperial gallon (UK) is 4,546 mL (160 fl oz). The Imperial gallon is about 20% larger. This converter uses US measurements.
