Thanks Peter. I think we need to call a
I saw an illegally addition to the label of a 1 litre bottle of olive oil in
Costco, Farnborough, United Kingdom. The label showed that it contained a quart
and a few fluid ounces of olive oil. It is illegal under UK law to add
supplementary units that use US gallons (Imperial gallons are permit
A few points that the respondent might like to make:
1. The US Constitution vests the control of weights and measures in
Congress. Congress have failed dismally to do their job – the few bits of
legislation that they passed included permission to use metric units in 1866,
ratification
Some will complain that the metric system is un-American. Point out to them
that that a square of land 100 metres by 100 meters (ie one hectare) is
sufficient to accommodate the Statue of Liberty. (See

Converting metric units customary units in direct speech is poor practice - it
ceases to be an accurate record of what was said.

An interesting thought, but there would be a knock-on effect - the newton,
pascal, joule, watt, volt, farad, ohm, siemens, weber, tesla and henry would
all cease to be coherent units. In particular:
*The newton is the force required to accelerate a mass of one kilogram by one
meter per second sq
il you translate them to the same language!). I
think that this makes it pretty obvious that SI is designed to be used by
everybody.

In the real world of engineering, many formulae contain a constant. In SI,
that constant might be something like ½, pi or 2*pi and seldom anything
else. The factor ½ often indicates that an integral has been used in
developing the formula, for example for formula for distance covered is
given by s=
