Remarks

This class behaves just like a Double representing a length in meters; 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 length representations, specifically inches, feet, yards, miles, U.S. survey feet, U.S. survey miles, light-seconds, and nautical miles. Metric conversions are handled simply by applying the needed SI conversion factor, for example:

Example

Convert length in meters to kilometers:

Copy

public double GetKilometers(Length meters)
{
    return meters / SI.Kilo;
}

This example converts feet to inches:

Copy

public double GetFeet(double inches)
{
    return Length.FromInches(inches).ToFeet();
}
