About These Units

Mach

Mach number is a dimensionless unit of speed defined as the ratio of an object's speed to the speed of sound. Mach 1 equals the speed of sound (approximately 343 m/s or 767 mph at sea level). Speeds above Mach 1 are called supersonic.

History

The Mach number is named after Austrian physicist Ernst Mach, who studied supersonic motion in the 19th century. It was introduced by Swiss aeronautical engineer Jakob Ackeret in 1929. The Concorde cruised at Mach 2.04, and the SR-71 Blackbird reached Mach 3.3.

mph

Miles per Hour

Miles per hour is a unit of speed expressing the number of miles traveled in one hour. It is the standard unit for vehicle speed limits and speedometers in the United States, United Kingdom, and a few other countries.

History

Miles per hour became widely used with the advent of automobile travel in the early 20th century. The US and UK use mph for all road speed limits. The highest speed limit in the United States is 85 mph on a stretch of Texas State Highway 130.

How these conversions work

Each category converts first through a base unit, then into the destination unit. That keeps the math consistent across metric and imperial systems and makes it easier to explain how results are generated.

When to double-check

Use these tools for planning, study, and everyday reference. For regulated, medical, engineering, or procurement work, confirm requirements against the official standard or specification you are working from.
