Re: Use Planck dimensions
The only proper dimensions to use are Planck dimensions since, with a few exceptions, they represent the extremes of what is measurable.
Planck Length = shortest length which has any meaning
Planck Time = shortest time period which has any meaning.
Plank Temperature = as hot as anything is ever likely to get
Of course, we'd have to get used to putting around 30 or 40 zeroes after everything, but at least it would get rid of the metric/imperial debate.
I'd love to go to my local builder's merchant and order a plank in Planck lengths.
Incidentally, the Plank energy (the energy content of a black hole that's one Planck length across) is roughly equal to ten gallons of petrol. I suppose that means my car has a "Planck tank".
