Gigawatt hour (3,600,000,000,000 J)
The gigawatt hour (symbol GWh) is a unit of energy equal to 3,600,000 megajoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in gigawatt hours is equal to the power in gigawatt multiplied by the time in hours.
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A horsepower-hour (hph or hp⋅h) is an outdated unit of energy, not used in the SI system of units.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.
