The speeds of vessels relative to the fluids in which they travel (boat speeds and air speeds) are measured in knots. For consistency, the speeds of navigational fluids (tidal streams, river currents and wind speeds) are also measured in knots. Thus, speed over the ground (SOG: ground speed (GS) in aircraft) and rate of progress towards a distant point ("velocity made good", VMG) are also given in knots.

My question is that, if we use knot for measuring the speed of ship then which indicator is used for measuring the speed of aeroplane? Please tell me.

Aeroplane speed is shown and measured in knots both the answers ship and aeroplane are right.

If knot is used in both ships and aeroplanes then how come this? Please explain.

It's both, a ship and an aeroplane. After all, aeroplane is also a ship.

1 knot = 1852 m/s.

Mostly used in ship but also used in air navigation.

Speed indicators on airplanes also display knots. (I am a pilot).

Friends please make it clear, it's Ship/Aeroplane ?

Knot is also used in Aeroplane to measure speed.
