## Remarks

This class behaves just like a Double representing a speed in meters per second; 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 speed representations, specifically miles per hour, kilometers per hour, feet per minute, inches per second, knots and Mach.

## Example

This example converts mph to km/h:
C#

    public double GetKilometersPerHour(double milesPerHour)
    {
        return Speed.FromMilesPerHour(milesPerHour).ToKilometersPerHour();
    }
