The US is moving along, the US might use feet and pounds but they do use Celsius. Also the rest of the world uses kilograms for mass of aircraft, fuel and baggage with some exceptions. All Carriers outside the US (including Canada) usebelieve kilograms for everything. In Europe they even use metres for take off and landing performance. I believe the rest of the planet uses feet for Altitude (except for china, Russia and the "stans", but they all use kilograms for aircraft mass and fuel weight. In larger aircraft they refer to "tonnes" of fuel instead of Kilograms.
