How many kilograms are in 30 liters of vegetable oil?

Answer

30 liters of vegetable oil weighs
27.6 kg

The density of vegetable oil is 0.92 kg/L (at 15.6–20 °C; peanut 0.914, olive 0.918, corn 0.922, soybean 0.927). The source gives a band of 0.914–0.927 kg/L.

How the mass of 30 liters of vegetable oil was worked out

mass = volume × density

0.92 kg/L × 30 L

=

27.6 kg

The density comes from FAO/INFOODS Density Database v2.0. At 15.6–20 °C; peanut 0.914, olive 0.918, corn 0.922, soybean 0.927.

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 30 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 vegetable oil that means 30 liters weighs 27.6 kg here, and one kilogram of it takes 1.09 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 30 liters of vegetable oil? (The answer is: 27.6). 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 30 liters of vegetable oil?

30 liters of vegetable oil weighs 27.6 kg

How do you work out the mass of 30 liters of vegetable oil?

Mass equals volume times density. The density of vegetable oil is 0.92 kg/L and the volume is 30 liters, which gives 27.6 kg.

How accurate is the density of vegetable oil?

The figure comes from FAO/INFOODS Density Database v2.0. At 15.6–20 °C; peanut 0.914, olive 0.918, corn 0.922, soybean 0.927. Within the band of 0.914–0.927 kg/L the answer shifts a little, and at household volumes that shift is usually smaller than the error of a kitchen scale.

Is 30 liters of vegetable oil heavier or lighter than water?

Vegetable oil has a density of 0.92 kg/L against 0.998 for water, so the same 30 liters weighs 27.6 kg instead of 29.9 kg. This is exactly why the everyday shorthand "a liter is a kilogram" only holds for water.
