Yard and Square Yard – A Short Note

A yard is a unit of length used in the imperial and U.S. customary systems. One yard equals 3 feet or 36 inches, which is approximately 0.9144 meters. Yards are commonly used to measure longer lengths or distances, such as in sports fields, fabric measurements, or landscaping.

A square yard (written as yd²) is a unit of area. It represents the area of a square that is one yard (3 feet) on each side. One square yard equals 9 square feet or 1,296 square inches, and approximately 0.836 square meters. Square yards are often used to measure surfaces like carpeting, lawns, or large fabric areas.

In short, a yard measures how long something is, while a square yard measures how much surface area it covers. Understanding both is useful in construction, gardening, and textile industries.

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.
