RE: NEC-LIST: Imperial metrics in the UK

David:

I enjoyed your note on metrification. Some of my friends at the U.S. Dept.
of Commerce NIST gave it a good shot trying to get the US to convert, but
to no avail. US business opted for the short term savings of not converting
rather than the lont-term benefits of standardization.

The last time I checked, only the US and Albania had not converted from a
global standpoint. Maybe Albania has by now converted.

Subject: NEC-LIST: Imperial metrics in the UK

Dear List,

In response to Jim Lux, my son is 11 and claims
"not to understand feet, inches, pounds, stones"
although he does understand pints as that is what
his consumption of milk, about 24 a week, comes in, but then,
they are Imperial pints which are 20 fl.oz. against the
US pint which is only 16. (Don't compare miles per
gallon!)

Seriously, the sooner everyone goes entirely metric,
the better for all of us. Australia is metricised.
Also, for antenna work the speed of light is very
very closely 0.3 metres per nanosecond, which is
a very memorable number (I teach it more loosely
as a foot a nanosecond to my students).

The UK has not yet converted from miles to kilometres
however. Kilometres is a good unit as it is supposed
to be 1/10,000 of the distance from a pole to the
equator. It makes satcoms calculations agreeable.

regards

David Jefferies.
