Understanding the conversion is helped by using the same time unit: 1 knot (per hour): 1852 meters/hour 1 meter per second: 3600 meters/hour So 2 knots is 37

Understanding the conversion is helped by using the same time unit: 1 knot (per hour): 1852 meters/hour 1 meter per second: 3600 meters/hour So 2 knots is 3704 meters/h, or less than 3% more than 1 meter/s. Good rule of thumb.
