Milligals to parts per million of g

Type a value in mGal to get it in ppm instantly.

1.02ppm

That's 2× as strong as a buried cavity, while an ore body is 2× stronger. A 70 kg person would weigh about 0.07138 g more or less.

What it means

How big is that anomaly?

Survey readings must be corrected for latitude, altitude, tides and terrain before the remaining anomaly means anything about the rock below.

The math

How to convert mGal to ppm

To convert milligals to parts per million of g, multiply by 1.01972.

Example: 1 mGal × 1.01972 = 1.01972 ppm.

In the other direction, 1 ppm = 0.980665 mGal.
