Conversion Formulae
Kilometres Per Hour to Metres Per Second Conversion Formula
The conversion formula for kilometres per hour to metres per second is quite simple:
1 kph = 0.27777778 m/s approximately
This can be calculated by taking the conversion factor for kilometres to metres (1000), thus 1 kilometre per hour equates to 1000 metres per hour. Then divide by the number of seconds in and hour (3600) 1000/3600 = 0.27777778.
Metres Per Second to Kilometres Per Hour Conversion Formula
The conversion formula for m/s to kph is simply the reciprocal of the kilometres per hour to metres per second formula:
1 m/s = 3.6 kph
To calculate this value take the conversion factor for metres to kilometres (1/1000 = 0.001 approx). Thus 1 metre per second equals 0.001 kilometres per second, so then multiply 0.001 x 3600 to get the metres per second to kilometres per hour conversion.
