How many liters are in 15 kilograms?

Answer

It depends on the density of the substance:
from 7.5 L (sand) to 29.4 L (LPG)

The question does not name a substance, and there is no single number for it: a kilogram fixes the mass, the volume comes from the density. For instance, 15 kilograms of water is 15 liters, while the same mass of gasoline takes 20.3 liters. The table below covers every substance.

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.

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 15 kilograms? 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 15 kilograms?

It depends on the density of the substance: from 7.5 L (sand) to 29.4 L (LPG)

Why does 15 kilograms not have one volume?

Because a kilogram measures mass and a liter measures volume, and density is what connects them. The mass stays the same while the room it takes does not: across the table below it runs from 7.5 to 29.4 liters. The lighter the substance, the more room the same kilogram needs.

How many liters is 15 kilograms of water?

Water is where the everyday rule comes from: 15 kilograms of water is 15 liters. Its density at 20 °C is 0.998 kg/L, two thousandths short of one kilogram per liter. For every other substance the number is different.

What takes the most and the least room at this mass?

The most compact is sand at 7.5 liters, the bulkiest is LPG at 29.4 liters. Note that this is the mirror image of the weight page: what is heaviest per liter is the most compact per kilogram.
