Power, Watt to horse power: 746W = 1 H.P. 1000W (1 kW) = (1000 / 746) H.P. = 1.34 H.P. Power, Watt to BTU/hour: 0.29307107 W = 1 BTU/h Energy, Joules to BTU: 1055.06 Joules = 1055.06 W/s = 1 BTU

Metric System:

735.5W = 1 H.P. 1000W (1kW) = (1000/735.5) H.P. = 1.36 H.P. 3.4121416 BTU/h = 1 W 0.9478 BTU = 1000 Joules = 1 KW/s

- Speed of light in vacuum= 1079252848.8 kilometer/hour = 299792458 meter/second

- Speed of sound in air [mach]= 1225.044 kilometer/hour = 340.29 meter/second

- 1 knot = 1.852 kilometer/hour = 0.514 meter/second

- 1 mile/hour (mph) = 1.609344 kilometer/hour (km/h), use above length converter for mile and kilometer

- 1 millibar = 1hpa (hectopascal)

- Liter: 1l = 1dm
^{3}(cubic decimeter)

- Tonn: 1t = 1000kg

- 1 are = 100 square meter = 100m
^{2}, 1 hectare=10,000m^{2}=0.01km^{2}

Example: 1km (kilometer) = 10
