##### fm/h²(femtometre per hour squared)

A unit of acceleration, like femtometer per hour squared (fm/h²), describes the rate at which the velocity of an object changes over time. Acceleration is typically measured in units like meters per second squared (m/s²) or feet per second squared (ft/s²).

Femtometer per hour squared (fm/h²) is an alternative and less common unit of acceleration. A femtometer (fm) is a very small unit of length, equal to 1x10^-15 meters (one quadrillionth of a meter). When the acceleration is measured in femtometers per hour squared, it means that for each hour that passes, the velocity of the object changes by a certain number of femtometers per second.

This unit is used in specific scientific contexts (often in particle physics or nanotechnology), where the distances involved are incredibly small, and the timescales involved are long compared to particle interactions. However, in most everyday situations, the more common units for acceleration like meters per second squared (m/s²) or feet per second squared (ft/s²) are used instead.

##### cGal(centigal)

A centigal (cGal) is a unit of acceleration commonly used in geophysics and geodesy to measure gravitational acceleration or gravity field variations. The term "centigal" is derived from the prefix "centi-" meaning one-hundredth (1/100) and "gal" named in honor of the Italian scientist Galileo Galilei. One centigal (1 cGal) is equal to one-hundredth of a Gal (0.01 Gal), equivalent to 1/100th of 1 cm/s² or 0.01 cm/s² (0.0001 m/s²). It is a non-SI (International System of Units) unit but is commonly used for expressing small gravity field variations and gravitational anomalies on Earth.
