Provided they left their Cutlasses & Tricorns out side.

To distinguish between the two tons, the smaller U.S. ton is called short, while the larger British ton is called long.

Bit like their gallons, smaller, so they can have more of them.

As to why the ton (not "British ton") is 2240lbs -

A ton equals 20cwt or hundredweight. Why is a hundredweight not 100lbs?

Because a hundredweight is equal to 4q or quarters, each of 28lbs.

And why is a quarter 28lbs?

Because a quarter is equal to 2st or stones, each of 14lbs.

All these strange numbers are because over the period from about the 14th to 19th century, it became necessary to tie together a number of weight units that were in general use for different commodities, so that common standards applied.

And the abbreviation "lbs"for pounds? It is an abbreviation of "librum", Latin for "pound". And this was a Roman weight unit about the same size.

Collectively known as avoirdupois, oddly a French word.

In the fourteenth century, English law was written in Norman-French, and the term has stuck ever since! "Pois" from Old French "peis", weight and "avoir" French for having.

Then just to keep you on your toes, there is a tonne which is 2,205 lbs

isn't a tonne 1000kg?

He's right you know.
According to Gargle, 1 Tonne = 2204.62 Lbs. So deadly close.

Why do the worlds navies still use knots to measure speed? tradition?

it fits perfectly into the nautical mile and also into space-time continuum....which no one knew about when they decided to use knots.

it , and the nautical mile also fit mathematically beautifully into speed of light and interplanetary and universal distance calculations, which the mile and kilometre do not , but again they didn't know that.

I think I remember Dr Karl talking about this on aunty one morning.....
