👉 The term "tachymeter" is a measurement of distance or speed. It is defined as the ratio between an object's length and time, measured in meters per second (m/s). This measurement can be used to determine distances and speeds accurately in various fields such as navigation, physics, engineering, and more. In addition to measuring distances and speeds, tachymeters are also used for other applications like tracking distance or speed of a moving object. They are commonly found in GPS systems
