How many liters are in 3 kilograms of water?

Answer

3 kilograms of water takes
3.01 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 3 kilograms of water was worked out

volume = mass ÷ density

3 kg ÷ 0.998 kg/L

3.01 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 3 kilograms takes 3.01 liters — 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 3 kilograms of water? (The answer is: 3.01). 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.

FAQ

How many liters are in 3 kilograms of water?

3 kilograms of water takes 3.01 L

How do you work out the volume of 3 kilograms of water?

Volume equals mass divided by density. The density of water is 0.998 kg/L and the mass is 3 kilograms, which gives 3.01 liters — the figure on this page is rounded, so dividing the two printed numbers can differ in the last digit.

How accurate is the density of water?

The figure comes from FAO/INFOODS Density Database v2.0. Liquid water at 20 °C; rounding to 1.00 kg/L is fine for everyday use.

And how much does 3 kilograms of water weigh per liter?

That is the opposite question, and it has its own page: one liter of water weighs 1 kg. This page starts from the mass and answers in liters; that one starts from the volume and answers in kilograms.
