Speed Conversion
MPH is statute miles per hour (used in many runabout speedometers). Canada marks its boat speed limits in kph or km/hr, which is kilometres per hour. Knots is nautical miles per hour and is measured by knotmeters in small boats and ships. A nautical mile is the distance of 1 minute of latitute, with 60 nautical miles in 1 degree of latitude. (Notice that you can divide km/hr in half to get an approximate speed in knots.)
