Electrical advice-30A circuits
[snip] No, power and energy are not the same thing. You must multiply power by time to get energy. Watts is power. Calories and BTU are energy. Sorry about the erroneous post. Mainly, I was replying to the nonsense about Calories being only in the body. -- Mark Lloyd http://notstupid.us/ " God... 1) The emperor has no clothes. 2) There is no emperor." |

For a real eye opener, look up 'arc flash protection ratings'. The protective equipment is rated in claories/sq cm. I know someone with a sign outside her house saying "beware of crack flashes". I think that means something somewhat different though. -- Mistress: Something between a mister and a mattress. |

They had some inflation when we started using it to describe food so it became the amount of energy to raise a kg of water one degree c. |

No, for power it's the kWh. We don't use BTUs in the UK anymore. Calories are only for your body. It's a unit of energy. Where the energy is is irrelevant. They can measure the Calorie content of food by burning it and measuring the heat produced. This isn't in anyone's body. Nobody uses calories outside of the human body. We'd be better using watts everywhere though. What??? -- Tekkie |
