“...so they put in liters instead of gallons.”
Doesn’t something as expensive as a 767 have a fuel gauge? And besides, I thought they measured onboard fuel by weight, not volume.
The fuel sensor was inoperative. So, ground crew used an approved method to measure the tank with a dipstick. But, he screwed up the calculation converting the measurement into fuel remaining.
Someone posted a link about the mishap earlier. You can find the details there.

I looked it up a little. Apparently the fuel gauges were not working (planes can still fly, depending on what is broken and whether they have a work around), so the ground crew checked manually (dipsticks), and told the flight crew how many liters there were...but the crew interpreted it as gallons...or maybe the ground crew stated gallons - either way, that was the mixup. When they do a manual check, it’s always by volume, then they convert it to weight to figure out the airplane’s characteristics.
