Pounds per gallon to specific gravity

Type a value in ppg to get it in SG instantly.

1.198SG

That's about the same as a typical drilling mud. At 1,000 m depth that column would exert about 117.5 bar.

What it means

How heavy is that mud?

Gradients are for a vertical well. In a deviated hole the pressure depends on true vertical depth, not on how much pipe is in the ground.

The math

How to convert ppg to SG

To convert pounds per gallon to specific gravity, multiply by 0.119826.

Example: 10 ppg × 0.119826 = 1.19826 SG.

In the other direction, 1 SG = 8.3454 ppg.
