Confusion over units during the process of metrication can sometimes lead to accidents . One of the most notable examples was during metrication in Canada . In 1983 , an Air Canada Boeing 767 , nicknamed the " Gimli Glider " following the incident , ran out of fuel in midflight . The incident was caused , in a large part , by the confusion over the conversion between litres , kilograms , and pounds , resulting in the aircraft receiving 22,300 pounds of fuel instead of the required 22,300 kg
