Convert between milliliters, liters, gallons, cups, cubic units, and more. Essential for cooking, chemistry, and engineering.

Volume conversion is the process of converting measurements of three-dimensional space from one unit to another. Volume represents the amount of space occupied by a substance or enclosed within a container.
Different systems use different volume units: the metric system uses liters and milliliters, while the US customary system uses gallons, quarts, pints, and cups. Scientific applications often use cubic units (cm³, m³).
Volume conversions are essential in cooking, chemistry, medicine, manufacturing, and everyday tasks like measuring liquids or comparing container sizes.
An Imperial gallon (UK) is about 20% larger than a US gallon. 1 Imperial gallon = 4.546 L, while 1 US gallon = 3.785 L. The UK also uses imperial pints and fluid ounces which differ from US measurements.
Yes! 1 milliliter (mL) is exactly equal to 1 cubic centimeter (cm³ or cc). They measure the same volume but mL is used for liquids while cm³ is common in science and medicine.
There are approximately 4.227 US cups in 1 liter. This is because 1 cup = 236.588 mL, so 1000 mL ÷ 236.588 ≈ 4.227 cups.
Volume measurements (cups, teaspoons) are convenient for home cooking as they don't require a scale. However, weight is more accurate, especially for baking, since volume can vary with how ingredients are packed.
Cubic units measure three-dimensional space. 1 cubic foot = 1 ft × 1 ft × 1 ft = 12 in × 12 in × 12 in = 1,728 cubic inches. Convert linear units first, then cube the conversion factor.
Medicine primarily uses metric units: milliliters (mL) for liquids and cubic centimeters (cc) for injections. Drops (gtt) are also used, though their exact volume varies. 1 mL is commonly approximated as 20 drops.
