Conversion from watt to metric horsepower example

Starting value Increment Accuracy

1 W = 0.00136 hk

Example: 1 watt = 0.00136 metric horsepower

Horsepower comes in flavours: the metric horsepower is about 735.5 W while the mechanical (imperial/US) horsepower is about 745.7 W, roughly 1.4% stronger. The same engine therefore shows a slightly lower number in hp than in European hk/PS figures. Always state which horsepower you mean.
'Kilowatts per hour' is a common slip of the tongue, power is measured in plain kilowatts. The kilowatt-hour (kWh) is energy: power multiplied by time. A machine draws 3 kW, and uses 3 kWh in one hour.
American air conditioners are rated in BTU/h, European ones in watts, 1 kW is about 3,412 BTU/h. A '9,000 BTU' unit is therefore about 2.6 kW. Divide BTU/h by 3,412 to get kilowatts.
'Calories burned per hour' is a power figure, not an amount of energy: 1 kcal/h is about 1.16 W. A run that burns 600 kcal in an hour corresponds to an average output of about 700 W.
