Pondering on units

[UKShootist]

I was pondering some reloading issues and I got to thinking about a 45/70 round. The most common bullet to use weighs about 405 grains, and a typical warmish load would produce a muzzle velocity of about 1,500 feet per second. All nice and comfortable. Then I converted the units. That translates to as near as dammit an ounce of lead travelling at over a thousand miles per hour! :shock:

Wait, you didn't convert to kilometers per hour ;)

[dbosman]

More impressive to scientists if you convert to the correct fraction of the speed of light.
:razz:

[dbosman]

0.0000014912 Speed of light

Why would he do that? His name is ukshootist not euroshootist. We still have miles per hour on our roads here, none of that metric nonsense.

Wasn't aware. Haven't been to the U.K. Everywhere else I've been in Europe has been in kilometers. Even Canada is metric :laugh:

It also looks like most things in the U.K. are metric. Buying fuel in liters and then having to convert to mpg would drive me nuts.

The US is metric too. Our foot is based on the international metre standard.

You can say whatever you want. The US uses imperial measurements. The country rejected the metric system before I was born for some reason. Base ten is much easier to work w/. It was it is and I have no qualms w/ it.

Too much math, I just want it to go BOOM!

Base 12 is what the cyclos used.
Or did they.......

Actually they were called Psychlos and they used base eleven.

That was a great book! Hubbard has one wild imagination, and I loved the storyline.

My old saying when I was working as an engineer and they started pushing the metric system in the 80's was "If God wanted us to use the metric system he would have had 10 disciples not 12"

Was brought up Imperial and converted to metric later. Now if I'm machining something I take all big cuts in millimetres and all small cuts in thou!
And yes, I do purchase fuel in litres and convert to mpg, doh!
Hey, just had a thought while writing this - you Americans DID have metric before us Limeys - 100 cents to the dollar (metric surely) when we had 12 pennies to the shilling and twenty shillings to the pound (oh yes, definitely Imperial).
By the way your gallon is 3.85 litres and ours is 4.54 litres - how come?

Rebellion of course. What else could we do?
I was raised with inches and feet but I convert to metric as needed. Too old to change basic thinking patterns now.

The funny thing is that you US folks only use some of the imperial system.

Inches and nothing less despite there being lines, barleycorns, poppyseeds, picas and points.
If pressed hard you can use a yard but no rods, fathoms, chains or furlongs before you do miles.

Grains, ounzes and pounds that's it.
No stones, quarters or hundredweight and dammed if you will use a ton.
Rather mess with millions of pounds.

Tounge in cheek folks ;-)

Well in Texas, until just recently, we used chains and rods - and varas for measuring land. We still use tons every day. ( of course there are tons and there are tonnes.) When I was a kid, stones were common and I still hear it occasionally. Hundredweight was used frequently in agriculture but I haven't heard it in years. Horse people use furlongs. Shooter use yards exclusively to measure ranges.

Printers use picas and points every day but I don't know if they are the same units you described.

I have heard of barley corns but have no idea how much it is and I never heard of poppy seeds except on buns and in dressings.

[tazman]

All this talk about barley, corn, poppy seeds,, buns, and dressing is making me hungry.

[oldblinddog]

In the USMC I qualified on both Meter ranges and Yard ranges with an M16A1.

I found it interesting that when I spent a month driving around the UK and Ireland recently that even though the UK claimed to be metric, you would find road distances measured in miles, exit distances measured in yards, and bridge clearances measured in meters.

Most items in grocery stores were sold by metric measurements, except for beer which was legally mandated to be sold by the pint. And their pint is 20 oz and the ounces are slightly different in size. All in all, I liked their pint size... <burp>

And we might as well measure muzzle velocity in furlongs per fortnight and kinetic energy in furlong-stones...
