Oil barrel unit is used globally

Similar to gallons, this unit has various definitions depending on the country of application. However, the only one used globally is the oil barrel unit, which equals 42 gallons. This unit originated many years ago when oil was transported in 50-gallon barrels, but it leaked or evaporated along the way, leaving only 42 gallons.
