Speed

Converts speed between knots, statute miles per hour, kilometers per hour, meters per second, and feet per second, with shortcuts for the common pairs. Pilots and drone operators use it for airspeed, wind, and groundspeed limits. Start with the speed converter. Pitfall: a knot is one nautical mile per hour, not one statute mile per hour. Weather reports give wind in knots, while many drone apps show mph or m/s, so convert before you compare.
