What is the gal (Gal) unit used for?

The gal (Gal) is a CGS unit of acceleration equal to 1 centimetre per second squared and is commonly used to express small accelerations or variations in gravitational acceleration, especially in geophysics and precision measurement.

How is the acceleration of gravity (g) unit defined?

One g is defined as the standard acceleration due to Earth's gravity, exactly 9.80665 m/s², and is used to express accelerations as multiples of Earth's gravitational acceleration.

Why convert Gal to acceleration of gravity (g)?

Converting Gal to g allows expressing small accelerations relative to Earth's gravity, facilitating comparisons in safety, engineering, and geophysical contexts.
