PGal(petagal)

In the field of acceleration, the unit PGal (petagal) is used to measure acceleration due to gravity or the force with which an object is pulled towards the Earth's surface. It is derived from the more common unit of acceleration: gal, which stands for "Galileo" in honor of Italian physicist and astronomer Galileo Galilei.

1 Gal is equivalent to 1 centimeter per second squared (1 cm/s²), which is the standard acceleration due to gravity at the Earth's surface. A petagal (PGal) is much larger than a gal and is given by:

1 PGal = 10¹⁵ Gal

In other words, 1 petagal is equal to 10¹⁵ centimeters per second squared (10¹⁵ cm/s²). It is an extremely large unit of acceleration and not frequently used in practical applications. It is mainly helpful when describing the gravitational effects in extreme astrophysical scenarios, such as near black holes or massive celestial bodies.

pGal(picogal)

The pGal (picogal) is a unit of acceleration used in geophysics and geodesy, specifically for measurements related to gravity anomalies and earth's gravity field. It stands for picogalileo, named after Galileo Galilei who first described the concept of acceleration.

A pGal is defined as one-trillionth (10^(-12)) of the standard acceleration due to gravity on Earth (g), which is approximately 9.80665 meters per second squared (m/s²). Therefore:

1 pGal = 10^(-12) x 9.80665 m/s² ≈ 9.80665 x 10^(-12) m/s²

This unit is used to express extremely small variations in the Earth's gravitational field, which can be relevant in various scientific disciplines, such as geophysics, earth sciences, and geodesy. These small variations can be caused by changes in mass distribution, density contrasts in the Earth's interior, or even the shape of the Earth. By measuring these variations in gravity, scientists can better understand Earth's structure, properties, and processes.

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.
