83.45ppg
That's 4.6× as heavy as a heavy weighted mud — nothing on our list beats it. At 1,000 m depth that column would exert about 980.7 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 SG to ppg
To convert specific gravity to pounds per gallon, multiply by 8.3454.
Example: 10 SG × 8.3454 = 83.454 ppg.
In the other direction, 1 ppg = 0.119826 SG.
