About this converter
Acceleration measures how quickly velocity changes over time. Meter per second squared (m/s²) is the SI unit, 1 foot per second squared equals exactly 0.3048 m/s², and standard gravity equals 9.80665 m/s².
This converter supports metric acceleration units, imperial acceleration units, Gal, and standard gravity. Mechanical engineers, vehicle dynamics teams, vibration analysts, geophysicists, physics students, and test-lab technicians use these conversions for motion studies, impact tests, seismic readings, and equipment specifications.

How to Convert m/s² to g
Meters per second squared to standard gravity
For example, 15 m/s² / 9.80665 = 1.52957 g.
Standard gravity to meters per second squared
For example, 2.5 g x 9.80665 = 24.5166 m/s².
When You Need to Convert Acceleration
Vehicle testing often reports acceleration in g, while physics equations use m/s². A braking event of 0.8 g equals 7.84532 m/s², which can be used to estimate stopping force and deceleration distance.
Geophysics uses Gal for gravity and seismic measurements. A reading of 250 Gal equals 2.5 m/s², making it easier to compare field data with engineering acceleration limits.
Machine vibration and motion control systems may use mm/s² or in/s² for small movements. Converting those values to m/s² helps engineers compare sensor data against SI-based equipment specifications.
