What Is This Tool?
This tool allows you to convert acceleration values from the gal (Gal), a CGS unit used for small accelerations, into the SI unit meter per square second (m/s²), enabling accurate comparisons and reporting in scientific and engineering contexts.
How to Use This Tool?
-
Enter the acceleration value measured in gal (Gal).
-
Select 'gal [Gal]' as the source unit and 'meter/square second' as the target unit.
-
Click the convert button to display the equivalent acceleration in m/s².
Key Features
-
Converts gal (Gal) — a unit equal to 1 cm/s² — to meter per square second (m/s²).
-
Easy, browser-based interface suitable for quick conversions.
-
Useful for gravity survey data, seismology, and accelerometer calibration.
-
Displays results in the internationally recognized SI acceleration unit.
Examples
-
50 Gal converts to 0.5 meter/square second (50 × 0.01).
-
120 Gal converts to 1.2 meter/square second (120 × 0.01).
Common Use Cases
-
Reporting gravity anomalies in gravimetry and gravity surveys.
-
Expressing small earthquake ground accelerations in seismology.
-
Calibrating sensitive accelerometers and interpreting precision acceleration data.
Tips & Best Practices
-
Always verify unit selection before conversion to ensure correct results.
-
Understand the context of measurements—gal is primarily used in geophysics and seismology.
-
Use high-precision instruments when dealing with very small acceleration values due to conversion scale.
Limitations
-
Conversions involving very small acceleration values demand precise measurement equipment due to the 1 Gal = 0.01 m/s² scale.
-
Gal units are uncommon outside geophysical fields, so familiarity with both units is important for multidisciplinary applications.
Frequently Asked Questions
-
What is a gal (Gal) unit?
-
The gal (Gal) is a CGS unit of acceleration equal to 1 centimetre per second squared, primarily used for expressing small accelerations including variations in gravitational acceleration.
-
Why convert gal to meter per square second?
-
Converting gal to the SI unit meter per square second allows for standardized reporting and comparison in science and engineering, especially when dealing with precise acceleration measurements.
-
In which fields is the gal unit commonly used?
-
The gal is mostly used in geophysics for gravity surveys, seismology for analyzing earthquake ground motion, and in calibrating sensitive accelerometers.
