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.
Convert the other way: SG to ppg
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.
