Usually, transport risk is computed by reference to the distance traveled by people, while for road traffic risk, only vehicle traveled distance is usually taken into account. [7] In the United States, the unit is used as an aggregate in yearly federal publications, while its usage is more sporadic in other countries.
1 gal-US (3.785 L, 0.833 gal-imp) of fuel can move a ton of cargo 857 km or 462 nmi by barge, or 337 km (209 mi) by rail, or 98 km (61 mi) by lorry. [142] Compare: Space Shuttle used to transport freight to the other side of the Earth (see above): 40 megajoules per tonne-kilometre. Net energy for lifting: 10 megajoules per tonne-kilometre.
For example, the freezing point of water is 0 °C and 32 °F, and a 5 °C change is the same as a 9 °F change. Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the ...
At one time, the definition of the nautical mile was based on the surface area of the Clarke ellipsoid. [further explanation needed] While the US used the full value of 1853.256 metres, in the British Commonwealth, this was rounded to 6080 feet (1853.184 m). These have been replaced by the international version (which rounds the 60th part of ...
A long ton, also called the weight ton (W/T), [1] imperial ton, or displacement ton, is equal to: 2,240 pounds (1,016.0 kilograms; 1.0160 metric tons) exactly 12% more than the 2,000 pounds of the North American short ton , being 20 long hundredweight (112 lb) rather than 20 short hundredweight (100 lb)
Hydrogen at atmospheric pressure has an energy density of 120 MJ/kg (113,738 BTU/kg), [88] 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.

As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. [1] Today, tonnes are more commonly used. [citation needed]
