Galileo (Unit) – A Short Note

The galileo (symbol: Gal) is a unit of acceleration used mainly in the field of geophysics, especially gravimetry, which measures the Earth's gravitational field.

One galileo is defined as:

1 Gal = 1 centimeter per second squared (1 cm/s²)

It is a non-SI (non-International System) unit, named after the Italian scientist Galileo Galilei in honor of his pioneering work on gravity and motion.

Because the Gal is a relatively large unit for precise gravity measurements, smaller subunits are often used:

• 
  

  1 milligal (mGal) = 0.001 Gal

  
  
• 
  

  1 microgal (µGal) = 0.000001 Gal

  
  

In practical terms, Earth's surface gravity is about 980 Gal, but variations in local gravity fields (due to terrain, density, etc.) are often measured in milligals or microgals.

The galileo unit is essential in geophysical surveys, oil exploration, and earthquake studies.

Picometer and Square Picometer – A Short Note

A picometer (symbol: pm) is a metric unit of length equal to:

1 picometer = 10⁻¹² meters

It is used to measure extremely small distances, typically at the atomic and molecular scale. For example, the diameter of a hydrogen atom is about 50–120 picometers. Scientists use picometers in fields like chemistry, nanotechnology, and physics to describe the size of atoms, chemical bonds, and tiny structures.

A square picometer (symbol: pm²) is a unit of area, representing a square with each side one picometer long:

1 pm² = (10⁻¹² m) × (10⁻¹² m) = 10⁻²⁴ m²

This unit is used to express extremely small surface areas, such as the cross-sectional area of atoms or molecules.

In summary:

• 
  

  Picometer (pm) measures ultra-small lengths

  
  
• 
  

  Square picometer (pm²) measures extremely small areas
