kg isn't a measure of force. And the world will be a nicer place once we retire the oddball prefixes of centi, deci, deka, and hecto.
- hansvm 6y ago> And the world will be a nicer place once we retire the oddball prefixes of centi, deci, deka, and hecto. Why? Is that just so we have fewer things to remember, or is there a more obvious benefit I'm missing?
- flubert 6y agoJust to be more consistent with the rest of the prefixes, which are all (integer) powers of 1,000. And because engineering notation is a thing. And because we normally group digits by the thousands (e.g. 1,000,000). Curious if anyone has come across a mechanical drawing or electrical schematic with oddball units like cm, hN-m, or deciFarads, daOhms and the like (daPa, hH). https://en.wikipedia.org/wiki/Engineering_notation https://en.wikipedia.org/wiki/Engineering_notation
- lopmotr 6y agoFewer things to remember is important because humans are useless at that. Hardly anyone will have an intuition for how much pressure a kg/cm^2 is as well as a N/cm^2 and a N/mm^2 and a kg/mm^2 and a kg/m^2 and PSI and a kPa ...
