When using the SI metric system we must be accurate in using the correct
symbols. The symbol for kilometers is km not Km. Therefore kilometers per
hour is km/h not Km/h. The SI system is made up of symbols not
abbreviations.
The US publications to refer to are:
NIST SP330 - The International System of Units (SI)
NIST SP811 - Guide for the Use of the International System of Units (SI)

Subject: Re: OT: SI units and precision
Rob,
The biggest stumbling block is getting our American colleagues to stop using
their Imperial (and modified Imperial) measures, AF screw threads & cups in
the kitchen and switch everything to SI units.
At the same time we need the Gov't here in the UK to switch from miles,
miles per hour, miles per gallon and pints to Km, Km/h, Litres / 100Km and
half litres (it's only 68ml short of a pint).
I'm old enough to know pounds & ounces, inches & feet, grammes, kilogrammes,
centimetres and metres so a switch to the full Metric system won't bother
me.
After we achieve that we can then consider the millis vs centis vs kilo vs
mega order of magnitude problems. But it's a minor problem when we have the
Luddites who won't use the nice weights and measures that the French
invented for us.
