# Energy / work converter

#### About this converter

This work and energy converter masters the SI-compliant units for work and energy (Joule J, Newtonmeter Nm), derived quantities and some other common units for work and energy. The conversion of energy into work is correct and can be understood as the conversion of energy into work that is done when this energy is transferred.

#### watt hour

The watt hour (Wh) is not a SI-compliant unit for work or energy, but it is a legal unit of measure and is mostly used in connection with the energy consumption of machines. The units in this converter that are related to the watt hour (Wh) are the watt second (Ws), the watt hour (Wh), the kilowatt hour (KWh) and the megawatt hour (MWh). In the SI-conforming unit, these correspond to Newton meters:

Unit | Newtonmeter |
---|---|

Watt second (Ws) | 1 |

Watt hour (Wh) | 3600 |

Kilowatt hour (KWh) | 3.6e6 |

Megawatt hour (MWh) | 3.6e9 |

#### The calorie

The calorie (cal) is an obsolete unit of energy, the thousand times (kilocalorie, kcal) is still used today in connection with food. Frequently, when using the term calories in connection with food, we actually mean the calories, which can lead to confusion. A calorie is the amount of energy required to heat one gram (milliliter) of water by one degree. One kilocalorie is the amount of energy required to heat one kilo (liter) of water by one degree Celsius. Instead of calorie, the term gram calorie is therefore often used to counter the confusion. The units correspond to Newton meters in the SI-compliant unit:

Unit | Newtonmeter |
---|---|

Calorie (cal) | 4.1868 |

Kilocalorie (kcal) | 4186.8 |

#### Energy

Energy is a fundamental physical quantity that plays a central role in all areas of physics as well as in technology, chemistry, biology and the economy. Your SI unit is Joule (J), which is identical to the Newton meter (Nm). Energy is the quantity that is preserved due to the time invariance of the natural laws, that is, the total energy of a closed system can neither be increased nor reduced (energy conservation rate). Many introductory texts define energy in a descriptive but not generally applicable form as the ability to do work.

#### Job

Work is the mechanical transfer of energy from one physical body to another. They say “work is being done on the body” or “work is being done”. This is done by applying force along a path to a physical body. The basic unit (SI unit) is therefore the Newton meter (Nm), which is identical to the Joule (J).

Unit | Newtonmeter |
---|---|

Watt second (Ws) | 1 |

Newton meters (Nm) | 1 |

Joule (J) | 1 |

Kilojoules (kJ) | 1000 |

Megajoules (MJ) | 1e6 |
