Ouch. That impacts a lot of physical definitions, like joules. -edit- On re-reading, I guess you weren't proposing changing the second, right?

- adestefan 13y agoThey're proposing changing the second and you're correct that it will mess up a ton of other units. The problem is they think the day is the base unit when it's actually the second.
- cynwoody 13y agoYes. There is a reason why we fiddle with stuff like leap-seconds instead of simply letting the second dilate ever so slightly, as Earth's rotation slows down ever so slightly, so that there are still exactly 86,400 seconds in a day. Since 1967, the second has been defined as 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.† The caesium atom is far more consistent than the Earth. †http://en.wikipedia.org/wiki/Second http://en.wikipedia.org/wiki/Second
