During which era did Mr Inch live?

Wasn't he at Cambridge with Furlong,
Yard, Chain and a Polish guy called
Rod Perch? I think that was the group
that first discovered length, or was
it distance? ;-)

(Actually derived from Latin, uncia, an ounce.)

In fact the SI units don't have a fixed rule for
capitalisation. When the unit is spelt out it should
not be capitalised - ohm, kelvin, farad - to avoid
confusion with the scientist. The abbreviation or
symbol should be capitalised for all those named
after people and for litre - Hz, L, V. The ohm is
normally written with a capital omega or written
in full as 'ohm'. Ohm at the beginning of a sentence
is capitalised.
