Amperes, Volts, Watts, Horsepower, BTUs
The many measures used in discussing energy, power and heat are all related and are not that complicated when you take a close look at them. After this you should know what a kWh is. If not, read more about kWh.
1 watt = 1 volt X 1 ampere
1 watt = 3.41 BTU
746 watts = 1 horsepower
Ampere: Measure of current.
Measures of power
- Watts, Kilowatts, Megawatts and Gigawatts (terms go up in measures of 1,000)
1 kilowatt (kW)= 1,000 watts
1 megawatt (MW)= 1,000 kW
1 gig watt (GW)= 1,000MW
- Horsepower (see above)
Measures of energy
- Watt hours, kilowatt hours
1 kilowatt hour = the amount of energy donated to a load of one kW in one hour.
Measures of heat
- BTU: quantity of heat needed to raise the temperature of 1 pound of water 1F. It is approximately the amount of heat created by lighting a common kitchen match.
