• Dekatherm (1,055,057,000 J)

  A dekatherm (dth) is a unit of energy used primarily to measure natural gas, developed in about 1972 by the Texas Eastern Transmission Corporation, a natural gas pipeline company.

It is also approximately equal to one thousand cubic feet (Mcf) of natural gas or exactly one Mcf of natural gas with a heating value of 1000 Btu/cf.

• Horsepower hour (2,684,519 J)

  A horsepower-hour (hph or hp⋅h) is an outdated unit of energy, not used in the SI system of units. The unit represents an amount of work a horse is supposed capable of delivering during an hour (1 (one) horsepower integrated over a time interval of an hour). The horsepower-hour is still used in the railroad industry when sharing motive power (locomotives.) For example, if Railroad A borrows a 2,500 horsepower locomotive from Railroad B and operates it for twelve hours, Railroad A owes a debt of (2,500 hp × 12 h) = 30,000 hp⋅h. Railroad A may repay the debt by loaning Railroad B a 3,000 horsepower locomotive for ten hours.
