##### 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.

##### Pm/h/s(petametre per hour per second)

Unit Pm/h/s (petameter per hour per second) represents the acceleration that corresponds to an object's velocity changing by 1 petameter per hour, every second. Acceleration is a measure of how quickly an object's velocity changes over time.

In this unit, petameter (Pm) represents a unit of distance or displacement equal to 1 × 10^15 meters, an hour is a unit of time equal to 60 minutes or 3600 seconds, and "per second" is the rate at which velocity is changing.

Putting it all together, 1 Pm/h/s means that an object's velocity is changing by 1 petameter per hour for every second that passes. This is a rare unit for measuring acceleration, as the values are extraordinarily large and not typically used in everyday measurements or standard physics applications.

##### pm/h/s(picometre per hour per second)

A picometer per hour per second (pm/h/s) is a unit used to specify acceleration, specifically describing how the velocity (or speed) of an object is changing over time. It precisely indicates how much the velocity alters by, in picometers per hour, during a time interval of one second.

A picometer (pm) is a very small unit of length measurement (1 picometer is equal to 1 x 10^-12 meters). Meanwhile, an hour is a unit of time equivalent to 3600 seconds. So, when we express acceleration in terms of picometers per hour per second, it breaks down to the velocity changing by a specific number of picometers every hour, and this value is measured per second.

This measurement unit is not commonly used in the field of acceleration, as its practical significance is limited due to the extremely small scale of picometers. Instead, the standard international unit for acceleration is meters per second squared (m/s²), which is more widely recognized and suitable for many situations. Nonetheless, pm/h/s can be used for specific instances requiring a more precise and extensive framework for measuring microscopic or nanoscale accelerations.
