Very close, Mr Goderator! I always knew the meter (metre) as unit of length based on the wavelength of light, but now I have learned that the original standard definition went something like this:

The birth of the metric system occurred in France in April 1790, when Charles Maurice de Tallyrand, then Bishop of Autun, placed before the National Assembly of France a plan based on a unit of length equal to the length of a pendulum that would make one full swing per second.
However, there were many recognized practical difficulties, including variations with temperature and values of gravitational force at different places on the surface of the earth. After scientific consideration a new unit of length equal to one ten-millionth of the length of the arc from the equator to the North Pole was recommended. In May 1793 this unit was given the name "Metre," derived from the Greek word metron, meaning "a measure." From the same word came the name of the new system. The new Republic of France adopted the recommendations of the French Academy of Sciences in 1795.

So how long does it take for a banana to age?

And my apologies for continuing the off-topicness of this thread.

7.8 kg/cm2 = 764.92 KPa = 110.94 lb/in2 = 7.65 Bar = 7.55 standard atmospheres

Unless the compression tester has the units labeled on it, I would be hesitant to assume what they are. Especially since Bar is a widely used metric unit.

Doesn't Canada use Imperial units, not the US?


-(stupid)
FSM states kg/cm2. Dont know what was used but I would imagine a rotary comp tester which would be kg/cm2, which would correlate nicely to his numbers.

That's why I put the big IF in my statement. I did some quick conversions but didn't check metric. I'm far from an ignorant American, and i'm sure you know that. Give me a globe, and I'll label every single country in the world.

I answered from my knowledge base and accordingly gave him a disclaimer
