Hubble's constant has unit km/sec/Mpc (which reduces to Hz with some minuscule coefficient.) On 2014-01-08, at 07:55, Ian S. Worthington wrote: > Here in Colombia everything is metric.

And there are the wire gauges, which depend on the metal, and increase numerically with decreasing diameter. I imagine medieval ironmongers who simply numbered the spools on shelves with no mutual coordination. And rod gauges (screw shanks, e.g.) which decrease numerically with decreasing diameter. > Hopefully I made my point in favor of SI ! -- gil
