# 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.

## Brief overview

1 watt = 1 volt X 1 ampere

1 watt = 3.41 BTU

746 watts = 1 horsepower

**Volt:**Measure of electrical potential

**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.

To Convert a measure of | Into | Use this equation: |
---|---|---|

Kilowatts | Watts | Kilowatts x 1000 |

Watts | Kilowatts | Watts x 0.001 |

Megawatts | Kilowatts | Megawatts x 1000 |

Kilowatts | Megawatts | Kilowatts x 0.001 |

Gigawatts | Megawatts | Gigawatts x 1000 |

Megawatts | Gigawatts | Megawatts x .001 |

Gigawatts | Watts | Gigawatts x 1 billion |

Watts | Btu/hour | Watts x 3.413 |

Btu/hour | Watts | Btu/hour x 0.293 |

Kilowatts | Btu/hour | Kilowatts x 3414 |

Btu/hour | Kilowatts | Btu/hour x 0.000293 |

Watts | Horsepower | Watts x 0.00134 |

Horsepower | Watts | Horsepower x 746 |

Kilowatts | Horsepower | Kilowatts x 1.34 |

Horsepower | Kilowatts | Horsepower x 0.746 |
