Inch and Square Inch 

An inch is a unit of length commonly used in the United States and other countries following the imperial system. It is equal to 1/12 of a foot or approximately 2.54 centimeters. Inches are typically used to measure small distances or dimensions, such as the size of a screen or the height of an object.

A square inch (written as in²) is a unit of area that represents a square with sides that are one inch in length. It is used to measure surface area, such as the area of a piece of paper, a screen, or a section of flooring. One square inch equals 6.45 square centimeters.

While inches measure one-dimensional length, square inches measure two-dimensional area. Understanding the difference between the two is important in fields such as construction, design, and manufacturing where both length and area are frequently calculated.

Gal – A Short Note

The Gal (symbol: Gal) is a unit of acceleration used primarily in geophysics and gravimetry to measure gravitational acceleration. It is named after Galileo Galilei, the famous Italian scientist who studied motion and gravity.

The Gal is defined as:

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

This means an object accelerating at 1 Gal gains 1 cm/s in speed every second.

Because the Gal is relatively large for precise measurements, smaller units are commonly used:

• 
  

  1 milligal (mGal) = 0.001 Gal

  
  
• 
  

  1 microgal (µGal) = 0.000001 Gal

  
  

Earth’s gravity at the surface is approximately 980 Gal, but geophysicists often measure small variations in gravity, so they typically use milligals or microgals.

The Gal is not an SI unit, but it is widely used in scientific fields related to the Earth, such as seismology, mining, and oil exploration.
