Feet per Second to Knots (ft/s to kn) Converter

1 foot per second equals 0.5924838 knots — multiply feet per second by 0.5924838 to convert. A knot is one nautical mile (1,852 meters) per hour, and one foot is 0.3048 meters, so 0.3048 × 3600 ÷ 1852 = 0.5924838 knots per ft/s.

The formula

To convert feet per second to knots, multiply by 0.5924838:

knots = ft/s × 0.5924838
Example: 10 × 0.5924838 = 5.924838 knots

To reverse it, divide knots by 0.5924838 (or multiply by 1.68781) to get ft/s.
