The kiloliter is a metric unit of volume that is 1000 times larger than a liter. It is equivalent to one cubic meter and is used to measure large amounts of liquid, such as in lakes or pools. The kiloliter is part of a hierarchy of ascending measurements in liters. It can be converted to other metric and standard measurements.
The kiloliter (kL), which is more commonly written kiloliter outside the United States, is a metric unit of measurement that refers to volume. It is 1000 times larger than a litre, which is a more recognizable unit of measurement for small amounts of liquid. The hierarchy of ascending measurements in the form of liters is as follows: millilitre, centilitre, decilitre, litre, decalitre, hectolitre and kilolitre. Other larger and smaller measurements are used much less frequently.
The use of liters derives from the metric systems developed in France, and the English name for liter is a close derivative of the French term, litron. The litron became popular for use in France after the French Revolution and the measurement quickly spread to other countries. Precise definition of the liter and its multiples shifted over time. Currently, a liter is .001 cubic meters, but it wasn’t quite equal to this number for a while. Only in 1964 did the General Conference of Weights and Measures (GCWM) decide to establish and standardize an exact ratio between kiloliters and cubic meters which made them equivalent.
Given this change, defining the kiloliter as a precise measure with cubic meter measurements hasn’t always been easy. Also, this measurement is not often used unless large amounts of volume are being evaluated. With standardization, however, the kiloliter is exactly equal to a single cubic meter, which simplifies mathematical calculations and conversions.
For those folks who don’t use metric measurements often, it also helps to get an idea of kiloiters translated into standard volume measurements, which are often used in places like the US. The kiloliter is equal to 33,814.02 fluid ounces, 4,226.75 cups, 2,113.38 pints, 1,056.69 quarts, 264.17 gallons, and 35.32 cubic feet. It helps to think about the size of a pound in half-gallon cartons of milk. Essentially, it takes over 500 cartons of whole milk to equal one kilolitre.
The size of this measurement suggests that it’s impractical for most everyday measurement tasks. Instead, it could be used to accurately discuss the volume of large amounts of liquid. Calculating the amount of water in a lake or stream might use kiloliters as a measure, or sometimes it can still use cubic meters instead. The number of liters of water in a pool could also be converted to kilolitres. The release of huge quantities of liquid pollutants or chemicals could also be measured in kilolitres.
Basically, kiloliters are the metric measure of volume and one is equal to 1000 liters or a single cubic metre. They tend to be used for measuring high volume levels, which means most people won’t be using this unit frequently for day-to-day activities. Kiloliters convert easily to other metric measurements and, with a little work, can also be converted to standard measurement systems.
