Oil Density Calculator

Oil density is a measure of how much mass a specific volume of oil contains. It is influenced by factors such as the type of oil (crude, fuel, or lubricant) and temperature. At standard conditions, the density of crude oil ranges between 800 to 1000 kg/m³, depending on its composition.

Oil density is often adjusted to a reference temperature, typically 15°C, to standardize measurements across different regions and industries.

How to Calculate Oil Density

The density of oil can be calculated using the following formula:

Density = Mass ÷ Volume

Where:

• Mass is the weight of the oil in kilograms (kg) or pounds (lb).
• Volume is the space the oil occupies, measured in cubic meters (m³) or cubic feet (ft³).

For temperature adjustments, the formula incorporates the coefficient of thermal expansion:

ρT = ρ15 × [1 - β × (T - 15)]

Where:

• ρT is the oil density at temperature T.
• ρ15 is the oil density at 15°C.
• β is the thermal expansion coefficient.

This formula accounts for the fact that oil expands or contracts with temperature changes.
