One slug is the mass of matter that requires 32.174 pounds of force to
give it an acceleration of 32.174 feet/second/second; which reduces
mathematically to 1 slug = 1 pound sec^2/foot.

One kilogram is the mass of matter that requires 9.81 newtons of force
to give it an acceleration of 9.81 meters/second/second; which reduces
mathematically to 1 kilogram = 1 newton sec^2/meter.

In their _own systems_ of measure - here on Earth's surface; where g is
the acceleration of free fall - the slug, and the kilogram are both
numerically equal to g/g, and a pound, and a newton of force are both
equal to1/g.

Don, when are we going to get back to the true definition of a pound?
A true pound is defined as equal to 7000 grains, and each grain is
equal to an English grown barleycorn!

Enough of this politically correct, French-loving definition of
..45359237 kilograms. The English barleycorn is the standard in our
system!

It's time we stopped kowtowing to the French and returned to the roots
of our own system of measure.

Any conversion factor between two truly independent systems of measure
should always be an irrational number!

By the way, Don, how many scruples are there in a dram?

That depends on the alcohol content; usually the more alky consumed,
the less are the scruples.

He's baaaaaaaaaack.....

Some definitions for you.

[1] 1 kg is an artifact somewhere in Paris. There is some talk
regarding replacing it. There are of course plenty of authorized
copies. The best I can do here -- and I don't know how much
precision one would get, as there are issues ranging from the
exact shape of the meniscus to the proper maintenance of the
temperature -- is a cube 10 cm on a side filled with
1 liter of 4 degree C deionized water, then sealed.

[2] 1 N is the force required to accelerate that 1 kg 1 m/s/s.

[3] If one applies 1 N for 1 second to that 1 kg, one ends
up with a kinetic energy of 1 J.

[4] 1 m is 1/299792458th the distance light travels in 1 second.

[5] 1 s is 9192631770 vibrations of a Cs-133 atom between two
specific states.

[6] 1 Pascal is 1 N force applied over 1 m^2 area. The Earth's
atmosphere is nominally 101325 Pascal, but varies.

[7] The Earth's gravity curvature is usually represented as
g=9.805 m/s/s, with about a 4-5% variation between
equator and poles, if I'm not mistaken. This is not
a definition, but a measurement.

A good point, Don. That brings up the subject of how important the
barleycorn is to the making of some of our favorite alcoholic beverages
such as scotch and bourbon. Truly a noble grain!

I think we should maintain our own standard barleycorn in an archive at
our Bureau of Standards, just as the French have their standard
kilogram in Paris.

Seven thousand standard barleycorns do a standard American pound make.

No better way to exercise our independence from France than by
establishing our own standards.

What do you think, Don?
