What is Mach ?

Mach (M) is a unit used to measure the speed of an object relative to the speed of sound in the surrounding medium, such as air or water. When something travels at Mach 1, it is moving at the speed of sound. This speed can vary depending on factors like temperature and altitude because the speed of sound changes with these conditions.

For example, if an aircraft is flying at Mach 2, it means it is moving at twice the speed of sound. The term "supersonic" refers to speeds faster than Mach 1, while "subsonic" means speeds slower than Mach 1.

Mach numbers provide a convenient way to describe high-speed movements, especially in aerospace engineering and aviation. They help engineers and pilots understand how close an object is to breaking the sound barrier and encountering aerodynamic effects associated with supersonic flight.


What is Knot ?

A Knot is a unit of speed primarily used in maritime and aviation contexts. It represents the speed at which a vessel or aircraft travels through water or air, respectively. One knot is equal to one nautical mile per hour, which translates to about 1.852 kilometers per hour or approximately 1.15078 miles per hour.

Historically, a knot was determined by counting the number of knots in a rope that unraveled from a reel over a specific time interval while a ship was underway. This method gave sailors a way to estimate their speed based on how quickly the knots passed through their hands.

Today, knots are still widely used in navigation, sailing, and aviation to measure speed over water or through the air, offering a standardized unit that remains crucial for safety and operational efficiency.
