[Value of MGal] = [Value of aGal] / 1.0E+24

[Value of aGal] = [Value of MGal] * 1.0E+24

##### 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.

##### MGal(megagal)

In the field of acceleration, the unit MGal (megagal) is used to express the magnitude of acceleration, specifically in relation to Earth's gravity. It is derived from the gal (Galileo), a unit of acceleration named after Galileo Galilei, who is known for his discoveries about the motion of falling bodies.

1 Gal is defined as an acceleration of 1 centimeter per second squared (1 cm/s^2). The MGal (megagal) term represents one million times the acceleration of 1 Gal, so 1 MGal is equal to 1,000,000 Gal or 1,000,000 cm/s^2.

It is important to note that the MGal unit is not a part of the International System of Units (SI), and it is mostly used in geophysics, seismic studies, and related fields to measure accelerations due to the Earth's gravity or processes acting within the Earth's crust.

##### mGal(milligal)

A milligal (mGal) is a unit of acceleration used in geophysics and geodesy to measure the strength of gravity. It is named after the French scientist Galileo Galilei, who extensively studied the behavior of objects in freefall.

1 mGal is equal to one-thousandth (0.001) of a gal, where 1 gal (galileo) is defined as 1 centimeter per second squared (1 cm/s²). Thus, 1 mGal is equal to 0.001 cm/s² or 1*10⁻⁵ m/s² (1*10⁻² m/s²).

In the field of geophysics, mGal is often used to express small variations in Earth's gravitational field or accelerations due to gravity. These tiny differences in gravity can be associated with factors such as the density of rock beneath Earth's surface or the varying mass distribution of the Earth.

Due to its small magnitude, the mGal unit is suitable for representing these local variations in Earth's gravity, which are often only a small fraction of the standard value of approximately 9.81 meters per second squared (9.81 m/s²).
