What is a kilolitre?

The kiloliter (kl) derived from SI (System International) volume unit with sides equal to one meter (1m) and, as such, is equivalent to one cubic meter. How many litres are in a kiloliter? One kiloliter (1kl) is equal to 1,000 litres (1000l). The kiloliter is used to measure liquid volume.

What is Volume?

Volume is three-dimensional space enclosed by a closed surface, such as the space occupied or contained by a material (solid, liquid, gas, or plasma) or form. Volume is also quantified using the SI-derived unit, m³. Volume is expressed by volume form in differential geometry and is an important Riemannian global invariant. In thermodynamics, the volume is a fundamental parameter and a conjugate variable for strain.


Any unit of length shall have the corresponding unit of volume: the volume of a cube the sides of which have the given length. For example, cm³ is the volume of a cube whose sides are one centimetre in length. 

The standard unit of volume in the International System of Units (SI) is the cubic meter (m³).


1 litre = (10 cm)3 = 1,000 cubic centimetres = 0.001 cubic metres,


1 cubic metre = 1,000 litres.

System International (SI)

The International System of Units is a modern metric system. It is the only system of measurement with official status in almost every country in the world. It consists of a coherent set of measurement units beginning with seven basic units: the second (unit of time with the symbol s), the meter (length, m), the kilogram (weight, kg), the ampere (electric current, A), the kelvin (thermodynamic temperature, K), the mole (quantity of material, mole) and the candela (luminous intensity, cd). The system allows for an unlimited number of additional units, called derived units, which can always be represented as products of the powers of the basic units. 

Twenty-two derived units were provided with special names and symbols. The SI selects seven units to be used as basic units, corresponding to seven basic physical quantities. They are the second, with the symbol s, which is the SI unit of the physical quantity of time; the meter, symbol m, the SI unit of length; the kilogram (kg, unit of mass); the ampere (A, electrical current); the thermodynamic temperature of the kelvin; the mole (mol, the quantity of substance); and the candela.

Solved Examples

1. How Many Litres in a Kilolitre?

Solution: The difference between the litre and the kilolitre is that the litre is the metric unit of the fluid measure, equal to one cubic decimeter symbol: l, l, while the kilolitre is the unit of the volume equivalent to the 1,000 litres symbol: kl.

1 kiloliters = 1,000 liters

2. How Many Centilitres in Kilolitres?

Solution: Centi-(symbol c) is a unit prefix of a factor of one hundredth in the metric system. The word “centi” was proposed in 1793 and adopted in 1795, comes from the Latin centum, meaning "hundred" It is mainly used in combination with a meter to form a centimetre, a common unit of length.

1 kiloliters = 1,00,000 centiliters

FAQs (Frequently Asked Questions)

1. What is the Kiloliter Used to Measure?

Solution: The kiloliter is used to measure liquid volume. Volume is a measure of how much space an object takes. For example, two shoe boxes together have twice the volume of one box, because they take up twice the amount of space. The volume of the container is generally understood to be the capacity of the container; i.e. the amount of fluid (gas or liquid) that the container may hold, rather than the amount of space that the container itself displaces. Volumes are also assigned to three-dimensional mathematical shapes.

2. What is Litre?

Solution: A metric unit of volume is the litre (SI symbols L and l,[1] other symbols used: l). It is equal to 1 cubic decimeter (dm³), 1000 cubic centimeters (cm³), or 0.001 cubic meters, respectively (m³). The volume of a cubic decimetre (or litre) is 10 cm x 10 cm x 10 cm and is therefore equivalent to one-thousandth of a cubic metre. A litre is a base unit that was used by the original French metric system. The word litre comes from an older French unit, the litron, whose name came from Greek, through Latin, where it was a unit of weight, not volume, and which amounted to about 0.831 litres. In some later iterations of the metric system, the litre was still used and is approved for use with the SI.
