A liter is a unit of volume, representing 1,000 cubic centimeters or milliliters, while a kilogram is a unit of mass, equivalent to 1,000 grams. Let’s understand the conversion from kg to litres.

Answer: One kilogram is approximately equal to 1 liter of water.

This relationship exists because the density of water at STP is close to 1 kilogram per liter (1 kg/L).

To put it simply, when you have 1 kilogram of water, it occupies a volume of 1 liter. This is a convenient and straightforward conversion, especially when dealing with water or other substances with similar densities.

Hence, 1 kg is approximately equal to 1 L of water at standard temperature and pressure (STP).
