In 1983 , a Boeing 767 ( which thanks to its pilot 's gliding skills landed safely and became known as the Gimli Glider ) ran out of fuel in mid-flight because of two mistakes in figuring the fuel supply of Air Canada 's first aircraft to use metric measurements . This accident was the result of both confusion due to the simultaneous use of metric and Imperial measures and confusion of mass and volume measures
