How many kilograms are in 1,000 liters of gasoline?

Answer

1,000 liters of gasoline weighs
740 kg

The density of gasoline is 0.74 kg/L (at 15 °C; the exact figure comes with the batch certificate). The source gives a band of 0.725–0.78 kg/L.

How the mass of 1,000 liters of gasoline was worked out

mass = volume × density

0.74 kg/L × 1,000 L

=

740 kg

The density comes from GOST 32513-2023 (Russian fuel standard). At 15 °C; the exact figure comes with the batch certificate.

Why a liter and a kilogram are not the same thing

A liter measures volume, a kilogram measures mass, and density is what ties them together: how many kilograms one liter of this particular substance comes to. The coincidence that makes people treat them as one thing is historical — in 1795 the gram was defined as the mass of one cubic centimeter of water, so a liter of water weighed a kilogram by construction. For anything else the equality breaks.

The extremes of this page make it obvious: one liter of LPG weighs 0.51 kg, while one liter of densely packed sand weighs 2 kg — four times more at the very same volume.

If the substance is not known in advance, start from how many kilograms are in 1,000 liters — the same volume across every substance at once.

The other way round: how much room a kilogram takes

This page starts from a volume and answers in kilograms. The opposite question — how many liters a given mass comes to — is what the kilograms to liters calculator is for. Both read the same density table, so the two pages agree wherever the answer is volume times density.

For gasoline that means 1,000 liters weighs 740 kg here, and one kilogram of it takes 1.35 liters there.

About "Liters to Kilograms" Calculator

This calculator converts liters to kilograms through the density of the substance: mass equals volume times density. A liter on its own has no weight — a liter of water weighs almost exactly a kilogram, a liter of honey close to one and a half, and a liter of gasoline about three quarters. For example, it can help you find out how many kilograms are in 1,000 liters of gasoline? (The answer is: 740). For bulk materials — cement, sand, soil, coal, vegetables — density depends on how the material is packed, so the page prints a range and names the state it was measured in, instead of passing one number off as a physical constant.

FAQ

How many kilograms are in 1,000 liters of gasoline?

1,000 liters of gasoline weighs 740 kg

How do you work out the mass of 1,000 liters of gasoline?

Mass equals volume times density. The density of gasoline is 0.74 kg/L and the volume is 1,000 liters, which gives 740 kg.

How accurate is the density of gasoline?

The figure comes from GOST 32513-2023 (Russian fuel standard). At 15 °C; the exact figure comes with the batch certificate. Within the band of 0.725–0.78 kg/L the answer shifts a little, and at household volumes that shift is usually smaller than the error of a kitchen scale.

Is 1,000 liters of gasoline heavier or lighter than water?

Gasoline has a density of 0.74 kg/L against 0.998 for water, so the same 1,000 liters weighs 740 kg instead of 998 kg. This is exactly why the everyday shorthand "a liter is a kilogram" only holds for water.
