EGal(exagal)

An exagal (EGal) is a unit of acceleration used in the field of geophysics to express gravitational acceleration. It is a non-SI (non-International System of Units) unit and is equivalent to 10^9 gals. A gal (short for Galileo) is a unit of acceleration that is equal to 1 centimeter per second squared (1 cm/s² or 0.01 m/s²). Therefore, 1 exagal is equal to 10^9 gals, which is equal to 1 billion centimeters per second squared (1 × 10⁹ cm/s² or 10^7 m/s²). This unit is primarily used in scientific research and geodesy to express large-scale gravitational acceleration or changes in acceleration.

µm/s²(micrometre per second squared)

The unit µm/s² (micrometre per second squared) is a derived unit of acceleration in the International System of Units (SI). It is used to express the rate of change of velocity with respect to time over a distance scale of micrometres.

One micrometre per second squared (1 µm/s²) represents an acceleration where an object's velocity changes by one micrometre per second (1 µm/s) every second. In other words, it signifies how quickly an object's velocity increases or decreases over time on a very small scale, in the order of micrometres (1 µm = 10^-6 meters).

This unit is typically used in fields such as microfluidics, micro-robotics, or any scientific research that involves the study of extremely small-scale motion and acceleration.
