Airpower Simplified: What is nautical miles, knots and Mach?
The common units for measuring distance on land are miles or kilometres (km). However, for marine or air (space) navigation, the preferred unit is nautical miles (NM). Similarly, speed is measured in km/hour or miles/hr for land vehicles, but the ships and aircraft use nautical miles/hr or knots.
