    Wind Speed Measurement Units and Conversion Factors    
    1 metre per second (m/s, ms-1)=2.237 miles per hour (mph)
    1 metre per second (m/s, ms-1)=1.9426 Knots (Kts)*
    1 metre per second (m/s, ms-1)=3.60 kilometres per hour (kph)
    1 Knot (Kts)*=0.515 metres per second (m/s, ms-1)
    1 Knot (Kts)*=1.152 miles per hour (mph)
    1 Knot (Kts)*=1.85 kilometres per hour (kph)
    1 mile per hour (mph)=0.447 metres per second (m/s, ms-1)
    1 mile per hour (mph)=0.868 Knots (Kts)*
    1 mile per hour (mph)=1.61 kilometres per hour (kph)

    Note: * There are actually two slightly different flavours of "Knots"...
    A "Knot" is defined as "nautical-miles per hour", in the UK a "nautical mile" is defined as 6080 feet whereas it is defined as 1.852Km (or 6076.12 feet) internationally which means that 0.0639% should be added to "UK knots" to get "International Knots". The small difference is generally not significant. We have always used the "UK knots" definition.
