How This Tool Works

This converter translates acceleration measurements from milligal (mGal) to meters per second squared (m/s2). The conversion factor is exact:

1 mGal = 0.00001 m/s2

To convert mGal to m/s2, multiply the mGal value by 0.00001. To convert m/s2 back to mGal, multiply by 100,000.

Why This Matters

Milligal measurements are common in gravimetry, geodesy, and seismology, where small acceleration changes can be meaningful. Converting to m/s2 keeps those values compatible with SI equations and engineering workflows.

For example, a reading of 50 mGal converts to 0.0005 m/s2, which can then be compared directly with other acceleration data.

Common Mistakes to Avoid

  • Do not confuse milligal with Gal. One mGal is one thousandth of a Gal.
  • Do not use 0.01 as the mGal-to-m/s2 factor; 0.01 applies to Gal, not milligal.
  • Keep acceleration separate from velocity or displacement measurements when standardizing field data.

Frequently Asked Questions

Common questions about the mGal to m/s² Converter

A milligal (mGal) equals 0.001 gal or 10^-5 m/s². It's the standard unit in gravity surveys.
