Specific gravity to kilograms per cubic meter
Type a value in SG to get it in kg/m³ instantly.
34,965.56kg/m³
That's 34× as heavy as oil sands bitumen — nothing on our list beats it. That is extra-heavy crude or bitumen, and it sinks in water.
What it means
How heavy is that oil?
API gravity is defined at 60 °F. Oil expands with heat, so a field measurement must be corrected to that temperature before the number means anything.
The math
How to convert SG to kg/m³
To convert specific gravity to kilograms per cubic meter, multiply by 999.016.
Example: 35 SG × 999.016 = 34,965.6 kg/m³.
In the other direction, 1 kg/m³ = 0.00100098 SG.
