The problem was that the original ground crew, and the flight crew (twice!), had forgotten that the new airliner used the metric system (as Canada was in the process of switching to the metric system, so the new planes purchased by Air Canada were being calibrated in metric units); as a result, they had all erroneously used the figure 1.77 lbs/liter for their specific gravity factor in the calculations, but what they should have used was 0.8 kg/liter.

Yep, it's
teh switching that causes planes to drop from the sky like paperweights.
Also, in this country we have advanced technology called "fuel gauges" that show "empty" as an E and "full" as an "F" with non-unit-denominated dashes to show half and quarter tanks (not
tenths metric fuckers) which it seems would prevent this problem.
Dismal, your ignorance is showing. As someone who knows, *intimately* the way aircraft fuel, CoG, and tank calculations are made because it's literally my job to program the behavior of those systems, and who has literally run into this exact same scenario before (fuel weight conversion issues causing aircraft failure albeit in simulated environments), it's no joke.
Fuel on an aircraft is calculated by the difference of the zero fuel weight and the gross weight of the aircraft. It has to be because the tanks on the aircraft are huge. And the fuel has to be calculated to within a close and exact margin of the trip requirements or they waste more fuel on carrying fuel, and that's their biggest overhead expense. So, again as a person whose biggest debugging problem happens to be when some guy doesn't configure every fuel display to the same units, this causes major issues. Simply put, having an incomplete or unexpected fuel measurement in an aircraft is probably the easiest way to guarantee a crash.
That said, if there was only one way to configure the fuel weights, it wouldn't be a problem. There's be one way to do it, and it would make my life at least half again easier.
