Volume Unit Converter

Convert between units of volume.

Supported Units

• Kiloliter (kL): The kiloliter is equal to 1,000 liters, which is the same volume as one cubic meter. It is commonly used for measuring large quantities of liquids such as municipal water consumption, swimming pool volumes, and industrial storage tanks. A typical household uses roughly 20 kiloliters of water per month. Water utilities bill customers in kiloliters, and agricultural irrigation volumes are also tracked in this unit.
• Liter (L): The liter is a metric unit of volume equal to 1,000 cubic centimeters or one cubic decimeter. It was introduced in France in 1795 as part of the metric system. The liter is one of the most widely used volume units in everyday life, appearing on beverage containers, fuel pumps, and cooking recipes around the world. In most countries, gasoline is sold by the liter, and engine displacement in automobiles is also expressed in liters.
• Milliliter (mL): The milliliter is one-thousandth of a liter and is equivalent to one cubic centimeter. It is the standard unit for small liquid volumes in medicine, where dosages are prescribed in milliliters (for example, "take 5 mL of cough syrup"). Cosmetics and personal care products list their volumes in milliliters. In cooking, a teaspoon holds approximately 5 mL, and measuring cups are often graduated in milliliters alongside other units.
• Cubic Meter (m³): The cubic meter is the SI derived unit of volume, representing the space occupied by a cube with sides of one meter. It is widely used in construction for quantities of concrete, earthwork, and fill material. In the energy sector, natural gas is traded and billed in cubic meters. One cubic meter equals 1,000 liters, making it a practical unit for large-scale liquid storage, water reservoirs, and shipping container capacities.
• Cubic Centimeter (cm³): The cubic centimeter is the volume of a cube with sides of one centimeter, numerically equal to one milliliter. It is commonly abbreviated as "cc" and used to express engine displacement in automobiles and motorcycles (for example, "a 1500 cc engine"). In medicine, syringe volumes are sometimes labeled in cubic centimeters. In laboratory science, the cubic centimeter is used for measuring the volumes of solid samples and liquids in graduated cylinders.
• Gallon (gal): The gallon is a unit of volume in the US customary system, defined as exactly 3.785411784 liters. In the United States, gasoline is sold by the gallon, and prices at gas stations are displayed per gallon. Milk, paint, and other household liquids are also commonly sold in gallon containers. Note that the imperial gallon used in the United Kingdom is a different, larger unit equal to approximately 4.546 liters. All conversions on this page use the US gallon.
• Quart (qt): The quart is a unit of volume in the US customary system, equal to one-quarter of a gallon or exactly 0.946352946 liters. The name derives from the Latin "quartus," meaning one-fourth. In the United States, motor oil is sold in quart bottles, and ice cream is commonly packaged in quart containers. Recipes for soups, stocks, and sauces often call for ingredients measured in quarts.
• Pint (pt): The pint is a unit of volume in the US customary system, equal to half a quart or exactly 0.473176473 liters. In the United States, fresh berries and small produce are sold in pint containers, and a "pint" of beer is a standard serving size in bars. In the United Kingdom, the imperial pint (approximately 568 mL) is larger than the US pint and is the traditional measure for draught beer in pubs. The word "pint" comes from the Old French "pinte."
• Cup (cup): The cup is a unit of volume used primarily in American cooking, defined as exactly 0.2365882365 liters, or half a US pint. Nearly all American recipes measure both liquid and dry ingredients in cups. One cup equals 8 US fluid ounces or approximately 236.6 milliliters. It is important to note that cup sizes vary by country: the Japanese cup is 200 mL, the Australian cup is 250 mL, and the Canadian metric cup is also 250 mL.
• Fluid Ounce (fl oz): The fluid ounce is a unit of volume in the US customary system, defined as exactly 29.5735295625 milliliters. It should not be confused with the ounce of mass. In the United States, beverage containers are labeled in fluid ounces—a standard soda can holds 12 fl oz (about 355 mL). Coffee shop sizes (8 oz, 12 oz, 16 oz) also refer to fluid ounces. Cosmetics and perfumes often list their volume in fluid ounces on the packaging.
• Tablespoon (tbsp): The tablespoon is a unit of volume commonly used in cooking, defined in the US system as exactly 14.78676478125 milliliters, or half a US fluid ounce. American recipes frequently call for tablespoons of ingredients such as oil, butter, and sauces. The abbreviation "tbsp" distinguishes it from the smaller teaspoon ("tsp"). Note that tablespoon sizes vary by country: the Australian tablespoon is 20 mL, while the metric tablespoon used in some countries is exactly 15 mL.
• Teaspoon (tsp): The teaspoon is a unit of volume used in cooking, defined in the US system as exactly 4.92892159375 milliliters, or one-third of a US tablespoon. It is the standard measure for small quantities of spices, salt, baking powder, and vanilla extract. In medicine, liquid doses are sometimes prescribed as "one teaspoon." The metric teaspoon, used in many countries, is defined as exactly 5 mL, which is very close to but not identical to the US teaspoon.
