Anyone for pounds (mass) per kilo pound (force)?

Aviation, because systems of units are there to be mixed.
The Imperial unit of mass is the slug
As someone who has lived through most of Australia's Metrication, I'd have to say that it all seemed pretty painless.
Even the daunting task of changing all the road signs was completed in a single month (July 1974).
The whole process started in 1972 (or thereabouts) and was mostly finished by 1978. From memory, the last group to change to metric was the real estate industry in 1988. It is funny though how some uses of imperial measures just won't die. New parents today, who have known nothing but metric measures their whole life, still publish their newborn child's weight in pounds and ounces even though they would have no idea what they themselves weigh in stones and pounds.
I don't know what system you're using, but pounds is the Imperial unit of force. The Imperial unit of mass is the slug. The SI unit of force is the Newton.
I was actually thinking that.Using quick Google statistics, Australia has over 810,000 km of public roads. The US has 3,573,000 km in highways alone. Not saying it can't be done, but it's considerably more difficult.
What about knots? I thought planes use knots for speed measurement.As WillDAQ said, it's aviation. As I said earlier, everything breaks down to inches-pounds-seconds in designing aircraft, so you avoid using things like slugs (because it confuses pilots) in favor of the three basic measurements (when possible).

Australia also has 1/15th the population and workforce of the USA .. so we have almost 4 times more road per head of population than the USA .... it should be much easier for the USA.
And narf, I don't see it being confused for kiloponds as that's an informal use/term for Newtons, which is SI, so I suppose unless someone isn't clear about which set you're using, maybe some knothead may confuse a kip for a kp? But generally speaking if you're designing something and are unclear about what units you're using perhaps you should pay more attention in team meetings.

It's just one letter away, and denotes the same type - force. Given a large enough team there are bound to be misunderstandings. It's happened before, sometimes catastrophically such as with the Mars Climate Orbiter.
We have half and half in the UK. Most things are sold in metric but they kinda cheat by selling the pound/ounce equivelant in grams (454g for a pound) and they sell 568ml of milk (pint). Everyone talks about height and weight in feet/inches and stones/pounds (1 stone = 14 pounds). It can be a bit confusing with things like fuel consumption as we buy our fuel in litres but try to work out the mpg. It may not be perfect but everyone learns both systems so if someone from europe says they're 185cm it doesn't really click with you straight away but you can kinda work out what it is roughly in feet
Pilots use knots. Controllers use knots. Customers use knots. Engineers and Designers use inches/second. Number crunching happens in those three measurments.
and thanks to best motoring i can do the same with kw - hp
