How many meters per second is 60 km / h

How many meters per second is 60 km / h

60 km / h = 60 000 m / 3 600 s = 50 / 3 M / S = 16.67 M / S

How many kilometers is 20000 meters

20 kilometers

How many kilometers is one nautical mile. The ship's speed / knots = kilometers / hour?

Nautical mile, sometimes represented by a disyllabic Chinese character with the symbol nm, is a unit of length used in navigation, usually equal to the international system of units 1852 meters
Traditionally, "nautical mile" is defined as a quarter of a circle around the earth (one circle equals 360 degrees, one degree equals 60 minutes, so the length of one nautical mile is twice the length of the meridian △ 360 △ 60). It can be measured by the change of the upper latitude of the meridian in the nautical chart. Since the earth is not a standard sphere, the distance of one degree is not exactly the same, so the length of the nautical mile is not fixed in fact
In 1929, the international external hydrological conference in Monaco defined 1 nautical mile as 1852 meters. Before that, the definition of 1 nautical mile was slightly different in different countries and regions. For example, before 1970, 1 nautical mile in Britain was 6080 feet, equivalent to 1853.184 meters, while that in the United States was 6080.2 feet, equivalent to 1853.249 meters
