In order to convert from U.S. units to metric units using the conversion factors shown in the following table, multiply the number of U.S. units (e.g., 2 pounds) times the conversion factor shown (0.45359237) to obtain the equivalent number in metric units (2 pounds times 0.45359237 pounds/kilograms = 0.90718474 kilograms)
1 short ton (2,000 lb) = 0.9071847 metric tons (t)
1 pounds (lb) = 0.45359237a kilograms (kg)
1 barrel of oil (bbl) = 0.1589873 cubic meters (m3)
1 cubic foot (ft3) = 0.02831685 cubic meters (m3)
1 U.S. gallon (gal) = 3.785412 = liters (L)
1 British thermal unit (Btu) = 1,055.055 852 62ab joules (J)
bThe Btu used in this table is the International Table Btu adopted by the Fifth International Conference on Properties of Steam, London, 1956.
Notes: Spaces have been inserted after every third digit to the right of the decimal for ease of reading. Most metric units belong to the International System of Units (SI), and the liter and metric ton are acceptable for use with the SI units.
