English measure of energy with regard to bullet energy is Ft/lbs. What is the comporable metric equivilent? Kg/M ? Joules? converting is easy but I just dont know what unit type you guys use to express bullet energy.

Dallan,
You dont go over the pond, I belive in Canada we are "required" to work with the metric system but no one does The English/Imperial system is better though
Anyways we work with Joules in the metric system

Doesn't 1 Joules= .7376 ft-lbs. ?

I belive your right althought most round up to 1J = .738ft/lb to be easyer on the calculator, I can be rusty havnt needed to use Joules ever execpt in chemistry for non-ft/lb applications

Vince,
Nothing wrong with that at all I'm young and most people I know hate the fact we are using the Imperial system in college, I'm the only one that honestly prefers it
The Metric system is backwards in my opinion, the inches/feet/yards/miles/pounds/Imperial Tons/gal/ etc work out better for me myself. I'm the only one I know here my age who can convert inches to yards and yards to miles.

I know the conversions of FT/LBS to Kg/M or Joules... I just wasnt sure which one is more predominantly used to describe this type of energy. I did some research and saw references to both hence my asking (I spent the evening working on the new PointBlank again)

Cool Dallan cant wait to see the new version
Anyways as far as I know Joules is more comman for it. I've only seen Joules listed myself.
Energy in general in the Metric system is always Joules. Kg/m seems more of a semi-metric/imperial way to measure energy, using metric units in a imperial statment when you have 2 values (such as ft/lb, in/lbs etc).

Well done Dimitri. I can still remember what we were taught in school all those years ago.....1760 yards, 5280 feet, 63,360 inches to the mile.
Cheers, Vince

Vince- how old are you
That hasn't been taught in schools for 25 years at least going by my father in law- who has been teaching for that long.
I used the imperial system because my dad did whenever we built anything when I was a kid- he's 76 now so that's understadable.
With the imperial system you can userstand what something is when thy say ai need a piece of 2x4 to whomp you stupid with V i need a piece of 50x100?? it just doesn't roll of the tongue wuite right.
I deal with European standards and have a quick convert program on my work pc otherwise I would be FUBAR working out what some of the measurements should be.
WTF is a decilitre anyway???
I'm 32 so I was taught metric at school but chose real maesurments to live my life by. Anywau how are you supposed to tel a g'smith to take x micrometres off when you can say take 10 thou of the bottom of that die and he knows exactly what you want.

Gidday Ogre, mate I was born in 1952 so I am 54 in May this year. I left school at the end of 1968 after completing 4th Form High School in Sydney.
The change to decimal currency happened in 1966 and I remember it well. Can't remember when the change over to metric happened, but it must have been in the early 70's because I remember chasing around to buy a gizmo for my 1963 EJ Holden that made your mph speedo read in kph.
Cheers, Vince

Thats 0.1 liters or 100ml, Remember everything is based on 10 in the metric system making it easyer then remembering Imperial conversions from one unit to the other.
The Metric System:
Lenth
1 millimeter = 0.001 meter
1 centimeter = 0.01 meter
1 decimeter = 0.1 meter
1 kilometer = 1000 meters
Mass
1 milligram = 0.001 gram
1 centigram = 0.01 gram
1 decigram = 0.1 gram
1 kilogram = 1000 grams
Volume:
1 milliliter = 0.001 liter
1 centiliter = 0.01 liter
1 deciliter = 0.1 liter
1 kiloliter = 1000 liters
The Imperial System
Lenth
1 foot = 12inches
1 yard = 3 feet = 36 inches
1 mile = 1,760 yards = 5,280 feet
Mass
1 ounce = 437.5 grains
1 pound = 16 ounces = 7000 grains
1 ton = 2240 pounds (British) = 35840 ounces = 15680000 grains
(In the US 1 ton is 2000lbs)
Volume (oz refers to fluid ounces)
1 pint = 20 oz.
1 quart = 2 pints = 40 oz.
1 gallon = 4 quarts = 8 pints = 160 oz.
Yes I realize that anyone in the US will disagree with these numbers but you got to remember that Canada used the British Standard not the American Standard.
The Differences:
1 U.S. fluid ounce = 1.041 Imperial fluid ounces = 29.57ml
1 Imperial fluid ounce = 0.961 U.S. fluid ounce = 28.41ml
1 liquid U.S. gallon = 0.833 Imperial gallon = 3.785L
1 Imperial gallon = 1.201 liquid U.S. gallons = 4.546L
The Metric system makes it easyer to convert without thinking I think since your just using multipuls of 10 where as in the Imperial system your not. But if you practice abit you can use the Imperial just as easy.

Who wants the view from England?
Metric has been phased in so slowly that we didn't know that it happened. They've left the sale of beer until last - there would have been a revolution if it went in first. We still do beer in pints - we do wine in metric. They're known as 'small' glasses and 'large' glasses...
It is now illegal to sell fruit and vegetables in imperial measures. They have to be sold in metric weights. We now buy by the 'bag' or by the 'handful'. Just like buying a woman If we did it any other way then we wouldn't understand. You'd end up buying a ton of carrots for your pet rabbit.
Petrol we do in litres. 5 litres to the gallon... just so's I know how much i'm getting. Nobody knows what the price of petrol is or how much it should be. Completely flummoxed. We still do distances in miles, if we changed over to KM we would be absolutely foo**d. You would end up packing food and blankets to do a trip of unknown kilometers and you would be there in half an hour. I now guage distance by time. At least they haven't changed that... My kids have learnt this unit of measure too "Are we there yet????"
When it comes to metric, we stand around nodding our heads so that we look like we understand and all the time we're thinking "What's that in pounds/pints/gallons...?"
Ammo is measured in grains, power in ft/lbs. A car's power output is rated by everyone as 'bhp' but the makers always rate is in 'PS' which means absolutely nothing to anybody.
Meters. A meter is a yard plus 3 inches. Stick your hand out to measure a vertical yard (which is really accurate!), turn your hand through 90 degrees and stick your thumb up. That's about a meter...
Kilometers. It is less than a mile, that I know. 80km is 50mph so best I don't go over 80 otherwise Officer Dibble will be having words. Can I visualise this metric system? Like Vince, the answer is 'no'. I am 6'2" tall and weigh 17 and a half stones. That's like 220 pounds or so, and in kilo's? I have no idea.
Incidentially, the metric system has been around for thousands of years - the greeks used it and so did the romans. It's nothing new and it does have some advantages for things like, erm, and the other thing... I grew up when England was changing over from imperial to metric so I struggle with both!
Keep well
D

Dam! We can still use it here. I dont think any law banning the imperial system would have passed here myself, it would be too hard considering we still have to use the imperial system with everything we import into the US
Daveyboy dont belive it when they tell you its been used for thousands of years they just want to make it easyer for them to force you to use it

1790 - France's Louis XVI authorized scientific investigations aimed at a reform of French weights and measures. These investigations led to the development of the first "metric" system. |
Just to let you know your weight in Kilo's is 100Kgs or so I know I weigh as much as you.
