Title: OK Braniacs - this is how much a kilogram weighs/equals....

Post by: Gadget on January 26, 2014, 10:06:15 PM: Funnily enough, I already knew this. The last of the physical of the Standards Internationalle (SI) units in the world. The metre is now defined as:
"The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second."

In turn the Second is defined as:

"The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.

Post by: Biggles on January 27, 2014, 03:22:26 PM: Well I'm glad we've got that settled. I'm just waiting for the definition of a litre so I can check my ST's fuel capacity and then the accuracy of the local servo's bowser.

The bike's weight checked out OK, thank Diesel.

Post by: HunterTodd on January 27, 2014, 03:45:05 PM: Well there you go they are all related.... the aforementioned metre when arranged in three dimensions (a cube) and filled with water at its triple point will weigh exactly 1000 kilograms! That is the beauty of the SI system. There are a minimum number of easily defined basic units, length temperature, time and I think energy. and every other unit is drived from those basic units. Unlike the mile which I think was defined by the length of a roman soldiers stride. and the horse power which was defined by the obvious. Bloody lucky I was not a roman soldier because the mile would be somewhat shorter than it is.
