##### Mm/h²(megametre per hour squared)

In the field of Acceleration, the unit Mm/h² (megametre per hour squared) represents an object's rate of change in velocity measured in megametres per hour squared. It is a non-standard unit to measure acceleration.

A megametre (Mm) is equal to one million (10^6) meters, and an hour squared (h²) refers to one hour multiplied by itself (1 hour x 1 hour = 1 hour²). Therefore, Mm/h² refers to the change in an object's velocity by 1 million meters (1 megametre) per hour, for every hour it is moving. It is a way to express extremely large accelerations, such as those found in celestial bodies or some astrophysical situations.

##### mm/h²(millimetre per hour squared)

The unit mm/h² (millimetre per hour squared) is used in the field of acceleration to denote the rate at which an object's velocity changes in terms of millimeters per hour, with respect to time. Specifically, it represents the increase in velocity (in millimeters) per hour, for each additional hour that passes.

For example, if an object has an acceleration of 1 mm/h², this means that its velocity is increasing at a rate of 1 millimeter per hour for every hour that goes by. After 1 hour, its velocity would have increased by 1 millimeter per hour (1 mm/h). After 2 hours, its velocity would have increased by another 2 millimeters per hour, for a total increase of 3 mm/h (1 + 2); and after 3 hours, its velocity would have increased by another 3 millimeters per hour, for a total increase of 6 mm/h (1 + 2 + 3).

This unit is typically used in applications where acceleration occurs at a very slow rate, such as in certain geological processes or industrial processes with slow rates of motion.

##### aGal(attogal)

An attogal (aGal) is a unit of acceleration, mainly used in geophysics and geodesy, to measure the gravitational field strength. It is derived from gal (Galileo), a non-SI unit initially introduced to express Earth's gravitational acceleration.

1 gal (Galileo) is equivalent to 1 centimeter per second squared (1 cm/s²). Attogal is a smaller unit in the Galileo system and is defined as one-quintillionth (10^(-18)) of the gal. So,

1 aGal (attogal) = 10^(-18) gal = 10^(-18) cm/s²

This extremely small unit of acceleration is used to represent variations in the Earth's gravitational field, as well as in precise measurements of gravity and related phenomena such as tidal forces or Earth's crust movements.
