The table of imperial avoirdupois mass is the same as the United States table up to one pound, but above that point, the tables differ. The imperial system has a hundredweight, defined as eight stone of 14 lb each, or 112 lb (50.802 345 44 kg), whereas a US hundredweight is 100 lb (45.359 237 kg). In both systems, 20 hundredweights make a ton.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline.
Hydrogen at atmospheric pressure has an energy density of 120 MJ/kg (113,738 BTU/kg), [122] by converting this energy density to a GGE, it is found that 1.011 kg of hydrogen is needed to meet the equivalent energy of one gallon of gasoline. This conversion factor can now be used to calculate the MPGe for this vehicle.
Prior to 1964, tires were all made to a 90% aspect ratio. Tire size was specified as the tire width in inches and the diameter in inches – for example, 6.50-15. [24] From 1965 to the early 1970s, tires were made to an 80% aspect ratio. Tire size was again specified by width in inches and diameter in inches.
The M939 series uses 11:00 R20 tires with two tires per side per axle in the rear (rear tandem duals). This allows a heavy load to be carried on improved roads and most US trucks in the past have used them. The M939A1 and M939A2 series instead use oversized 14:00 R20 tires with a single tire on each side per axle, still with a tandem setup.

Tundra tires up to 26 in (66 cm) may be fitted. [1] [3] The aircraft has a typical empty weight of 985 lb (447 kg) and a gross weight of 1,800 lb (820 kg), giving a useful load of 815 lb (370 kg). With full fuel of 31.75 U.S. gallons (120.2 L; 26.44 imp gal) the payload for the crew/pilot, passengers and baggage is 625 lb (283 kg). [1] [3]
