How much does 100 gallons of diesel weigh?

Answer

100 US gallons of diesel weighs
696 lbs

The density of diesel is 0.834 kg/L (at 15 °C, summer grade; winter and arctic grades are lighter), so one US gallon of it weighs 6.96 lbs.

In imperial (UK) gallons of 4.54609 L instead of 3.785411784 L, 100 UK gallons of diesel would weigh 835.9 lbs.

How the weight of 100 gallons of diesel was worked out

pounds = gallons × density (kg/L) × 3.785411784 ÷ 0.45359237

A US gallon is exactly 3.785411784 liters and a pound is exactly 0.45359237 kilograms, so the density in kilograms per liter turns into pounds per gallon by multiplying by the first and dividing by the second.

100 gal × 0.834 kg/L × 3.785411784 ÷ 0.45359237

≈

696 lbs

(six hundred ninety-six lbs)

The density comes from GOST 32511-2013 (Russian fuel standard): at 15 °C, summer grade; winter and arctic grades are lighter.

Why the same gallon weighs differently

A gallon measures volume, a pound measures weight, and density is what ties them together: how many pounds one US gallon of this particular substance comes to. Water is the everyday reference at 8.33 lbs per gallon, and everything else sits above or below it.

Across this page the spread is wide: one US gallon of propane weighs 4.24 lbs, one US gallon of milk 8.6 lbs — at the very same volume.

If the substance is not known in advance, start from how many pounds 100 gallons is — the same volume across every substance at once.

The other way round: how many gallons a weight fills

This page starts from a volume and answers in pounds. The opposite question — how many gallons a given weight comes to — is what the pounds to gallons calculator is for, and in metric units the same question is kilograms to liters. All of them read one density table, so their numbers agree.

For diesel that means 100 gallons weighs 696 lbs here, and one pound of it fills 0.14 gallons there.

About "Gallons to Pounds" Calculator

This calculator converts US gallons to pounds through the density of the substance: weight equals volume times density. A gallon on its own has no weight — a gallon of water weighs 8.33 lbs, a gallon of gasoline 6.18 lbs and a gallon of propane only 4.24 lbs. When no substance is named, the answer is for water, and the table shows every other liquid next to it. For example, it can help you find out how much does 100 gallons of diesel weigh? (The answer is: 696). The gallon here is the US liquid gallon of 231 cubic inches; the imperial gallon used in the UK is a fifth larger, and every result page names what the same number of imperial gallons would weigh.

FAQ

How much does 100 gallons of diesel weigh?

100 US gallons of diesel weighs 696 lbs

How do you work out the weight of 100 gallons of diesel?

Weight equals volume times density. The density of diesel is 0.834 kg/L and a US gallon is exactly 3.785411784 liters and a pound is exactly 0.45359237 kilograms, so 100 gallons weighs 696 lbs — the figure is rounded, so multiplying the printed numbers can differ in the last digit.

How accurate is the density of diesel?

The figure comes from GOST 32511-2013 (Russian fuel standard): at 15 °C, summer grade; winter and arctic grades are lighter. Within the band of 0.82–0.845 kg/L one US gallon weighs 6.84–7.05 lbs.

Is 100 gallons of diesel heavier or lighter than water?

Diesel has a density of 0.834 kg/L against 0.998 for water, so the same 100 gallons weighs 696 lbs instead of 832.9 lbs — lighter.
