Remarks

This class behaves just like a Double representing an energy in joules; 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 energy representations, specifically watt-hours, BTU, Celsius heat unit, liter-atmosphere, calorie, horsepower-hour, barrel of oil and ton of coal. Metric conversions are handled simply by applying the needed SI conversion factor, for example:

Example

Convert energy in joules to megajoules:

Copy

public double GetMegajoules(Energy joules)
{
    return joules / SI.Mega;
}

This example converts megajoules to kilowatt-hours:

Copy

public double GetKilowattHours(double megajoules)
{
    return (new Energy(megajoules * SI.Mega)).ToWattHours() / SI.Kilo;
}

This example converts kilowatt-hours to megawatt-hours:

Copy

public double GetMegawattHours(double kilowattHours)
{
    return (kilowattHours * SI.Kilo) / SI.Mega;
}
