How Much Does a Litre of Diesel Weigh? Complete Weight & Volume Chart

Whether you manage an agricultural operation, run a commercial freight fleet, or calculate fuel loads for plant machinery, knowing the exact weight of diesel fuel is essential for staying legal on transport axle limits.

A common assumption is that diesel and petrol weigh roughly the same. In reality, diesel is significantly heavier and denser than petrol.

1 Litre of Automotive Diesel (EN 590) = 0.835 Kilograms (835 grams) Imperial Equivalent = 1.841 Pounds (lbs) = 29.45 Ounces Specific Gravity = 0.835 (Floats on water, but sinks under petrol) 1 US Gallon of Diesel = 7.05 Pounds (3.20 kg) 

At the standard reference temperature of 15°C (59°F), one litre of standard Ultra-Low Sulfur Diesel (ULSD) weighs 0.835 kilograms (1.841 pounds).

Under international specifications (such as European standard EN 590 or ASTM D975 in North America), commercial diesel density is legally regulated between 0.820 kg/L and 0.845 kg/L.

Diesel Weight by Common Container Volumes

Here is a practical conversion table calculating diesel weight across standard canisters, drums, and storage tanks based on standard density (0.835 kg/L):

Diesel vs. Petrol: Why Is Diesel Heavier?

Diesel and petrol are both refined from crude oil, but they boil off at different stages of fractional distillation:

graph TD
    A[Crude Oil Distillation] --> B[Gasoline / Petrol: C4-C12 Molecules]
    A --> C[Diesel Fuel: C10-C22 Molecules]
    B --> D[Density: ~0.74 kg/L (Lighter)]
    C --> E[Density: ~0.835 kg/L (Denser)]

• Gasoline is composed of smaller, lighter molecules containing 4 to 12 carbon atoms.
• Diesel consists of longer, heavier hydrocarbon chains containing 10 to 22 carbon atoms.

Because these longer molecules pack together more tightly, diesel contains more mass per unit volume. This extra mass is also why diesel contains approximately 10% to 15% more energy per litre than petrol (~36 MJ/L vs ~32 MJ/L), directly explaining diesel's superior thermal efficiency.

EN 590 Standards and Climate Grade Variances

Commercial diesel is not identical everywhere. Standards bodies define specific density windows to protect high-pressure fuel injection systems:

European Standard EN 590

Legally mandates diesel density between 0.820 and 0.845 kg/L at 15°C. Most major oil brands (Shell, BP, TotalEnergies) target 0.835 kg/L for their baseline pump fuel.

North American ASTM D975 (No. 2-D ULSD)

Typically exhibits a density range of 0.830 to 0.850 kg/L, depending on regional crude stock sources.

Winter Diesel & Arctic Blends (No. 1-D)

In freezing climates, standard diesel forms wax paraffin crystals that clog fuel filters (cloud point). Refineries blend kerosene or light distillates into winter diesel to prevent gelling.

• Summer Diesel: Density ~0.835–0.845 kg/L
• Winterized Diesel: Density ~0.820–0.830 kg/L (lighter because kerosene density is ~0.820 kg/L)
• Arctic Diesel: Density can dip as low as 0.805–0.815 kg/L

Temperature and Thermal Expansion in Commercial Fleets

Diesel expands as ambient temperatures rise. The volumetric thermal expansion coefficient for diesel is approximately β ≈ 0.00095 per °C.

Here is how temperature shifts the density and weight of 1,000 litres of diesel:

For fleet operators purchasing wholesale fuel in bulk tankers (35,000 to 45,000 litres), this temperature coefficient accounts for hundreds of kilograms of difference, which is why commercial invoices apply temperature-compensation factors.

Frequently Asked Questions

How much does 100 litres of diesel weigh?

At standard 15°C temperature, 100 litres of automotive diesel weighs 83.5 kilograms (184.1 pounds).

How much does a full tank of diesel weigh in a truck?

In a long-haul commercial tractor with dual 400-liter fuel tanks (800 liters total), the fuel weighs 668 kilograms (1,473 pounds). For a standard passenger SUV with a 70-liter tank, full diesel fuel adds 58.5 kilograms (128.9 pounds).

How do you convert diesel litres to kilograms?

Multiply your volume in litres by 0.835: Mass (kg) = Litres × 0.835 For reverse calculations (kilograms to litres), divide your mass in kilograms by 0.835.
