About Power conversion
Power is how fast energy is used, car engines in horsepower, home appliances in watts, and large systems in kilowatts. Fiction Units converts between them so you can compare a 200 hp engine to a 150 kW electric motor or check if a generator will run your tools.
1 mechanical horsepower is about 746 watts, so a typical car at 150 hp is about 112 kilowatts, the same unit your electric bill uses.
Units supported: Watts, kilowatts, horsepower, BTU/hour.
