How many liters are in 1 kilogram of water?
Answer
1 kilogram of water takes
1 L
The density of water is 0.998 kg/L (liquid water at 20 °C; rounding to 1.00 kg/L is fine for everyday use).
How the volume of 1 kilogram of water was worked out
volume = mass ÷ density
1 kg ÷ 0.998 kg/L
≈1 L
The density comes from FAO/INFOODS Density Database v2.0. Liquid water at 20 °C; rounding to 1.00 kg/L is fine for everyday use.
The other way round: what a liter of this weighs
This page starts from a mass and answers in liters. The opposite question — how much a given volume weighs — is what the liters to kilograms calculator is for. Both read the same density table, so the two pages agree wherever the answer is volume times density.
For water the density is 0.998 kg/L, so 1 kilogram takes 1 liter — and one liter of it weighs 1 kg.

About "Kilograms to Liters" Calculator
This calculator converts kilograms to liters through the density of the substance: volume equals mass divided by density. The heavier the substance, the less room the same kilogram takes — one kilogram of honey is 0.7 liters, while one kilogram of liquefied gas is almost two. For example, it can help you find out how many liters are in 1 kilogram of water? (The answer is: 1). For bulk materials the answer is a range, and it is inverted against the weight page: the denser the packing, the smaller the volume of the same mass.
