For example, if a unit has the symbol "imp gal", and if the link is @[[Gallon]], then if the symbol is linked, it would appear as "imp gal" ("imp" and "gal" link two different articles). The Links section defines exceptions for unit codes with an SI prefix, where the linked article is different from that of the base unit.
Megawatt-hours (MWh), gigawatt-hours (GWh), and terawatt-hours (TWh) are often used for metering larger amounts of electrical energy to industrial customers and in power generation. The terawatt-hour and petawatt-hour (PWh) units are large enough to conveniently express the annual electricity generation for whole countries and the world energy ...

One terawatt hour of energy is equal to a sustained power delivery of one terawatt for one hour, or approximately 114 megawatts for a period of one year: Power output = energy / time 1 terawatt hour per year = 1 × 10 12 W·h / (365 days × 24 hours per day) ≈ 114 million watts, equivalent to approximately 114 megawatts of constant power output.
