Mach (speed of sound)
Definition
Mach is a dimensionless unit representing the ratio of an object's speed to the local speed of sound. Mach 1 equals the speed of sound (approximately 343 m/s or 1,235 km/h at sea level in standard conditions).
History
The Mach number was named after Ernst Mach, an Austrian physicist who studied supersonic motion in the 19th century. It became critical during World War II and the subsequent development of jet and rocket aircraft.
Current use
Mach numbers are essential in aerospace engineering, military aviation, and supersonic transport. Fighter jets, commercial aircraft approaching transonic speeds, and spacecraft re-entry velocities are all described using Mach.
Miles per hour (mph)
Definition
Miles per hour (mph) is an imperial unit of speed expressing the number of statute miles traveled in one hour. 1 mph ≈ 1.60934 km/h.
History
Miles per hour became the standard speed unit as horse-drawn transport gave way to automobiles in the early 20th century. The United States and United Kingdom adopted mph for their road systems.
Current use
Miles per hour is the official unit for road speed limits and vehicle speedometers in the United States, United Kingdom, and a few other countries. It is also used in baseball (pitch speed) and informal speed references.
