There is a Hemingway short story about an American boy brought up in France who has his temperature measured by an American doctor who uses the Fahrenheit scale and the boy believes he is going to die. Tullio |

It happens quite often that units are mixed up. In Canada, it was an airplane that was fueled with the wrong amount. Instead of kilograms it became pounds and it means half as much fuel. The pilot discovers it first when they flown about halfway. They find an alternate aerodrome that is deserted but unfortunately the engines stop before they will land. Fortunately, the pilot is used with gliders and use special maneuvers to land. Then they discover that the airport is not abandoned. It is a drag race that is going on there and it's two boys who are cycling on it. Even here it ends happily and no one was injured. https://www.youtube.com/watch?v=lTRAQAzey4w |

Centigrade lasted until 1948 when it was renamed Celsius, and it is also called Kelvin by the scientists. The Kelvin is the primary unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. T[°C] = T[K] − 273,15 The temperature in my country is about 270 K right now. |

Centigrade lasted until 1948 when it was renamed Celsius, and it is also called Kelvin by the scientists. The temperature of the cosmic background radiation is about 4 K. |

Celsius and Kelvin use the same unit, but are very different measurement scales, generally used for very different purposes. And Chris, water freezes at 0C and boils at 100C at one very specific pressure, in one very specific atmosphere. And it has to be very pure water. All these measurement systems and units are arbitrary. As I said before, it just depends which one you get used to. This sums it up nicely. |

Celsius and Kelvin uses the same measurement scale. T[°C] = T[K] − 273,15 |

No, 2.7 K. Tullio |

No, 2.7 K. Thanks Tullio. Awfully cold anyway. |

Yes, by it is not uniform and shows some variations, as measured by spacecrafts and terrestrial infrared telescopes, like the one at the South Pole which caused a rumor when they said that the polarization of the Cosmic Microwave Background showed the signs of primordial gravitational waves.Now it is all in doubt again, but it seems that the Universe has a colder part and a warmer part, no one knows why.

WMAP shows the differences of temperature in universe. The red part is Milky Way. |

So like one meter is the distance travelled by light Yes. Wich means that the Mississippi river is very small. |

They play hockey in Mississippi! You mean like playing hockey on the Mississippi river? Would like to see Börje Samling and Wayne Gretsky doing that. |

Wayne Gretsky is Canadian! |

Wayne Gretsky is Canadian! Of course he is:) Just like Börje Salming who is Swedish. Actually he is a lap. |
