JavaScript supports the use of structures, but not the declaration of new ones.

Remarks

This class behaves just like a Double representing a power in watts; it is implicitly castable to and from a Double and therefore can be generally used "as" a double, but it has the advantage of handling conversions to and from other power representations, specifically horsepower, metric horsepower, boiler horsepower, BTU per second, calorie per second, and liter-atmosphere per second. Metric conversions are handled simply by applying the needed SI conversion factor, for example:

Example

Convert power in watts to megawatts:

Copy

public double GetMegawatts(Power watts)
{
    return watts / SI.Mega;
}

This example converts megawatts to mechanical horsepower:

Copy

public double GetHorsepower(double megawatts)
{
    return (new Power(megawatts * SI.Mega)).ToHorsepower();
}
