Feet per Second to Knot Converter
Speed · unit-converter
Convert Feet per Second to Knot with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through meters per second with fixed definitions (knot, international mile, Mach 1 = ISA sea level, Beaufort WMO bands at 10 m, vacuum c, plus linear SI and imperial rate units like km/s, fpm, ips, cm/s, and mm/s).
About Feet per Second
Feet per second appears in ballistics, engineering, and some US sports contexts; it relates to imperial length per second.
About Knot
The knot is one nautical mile per hour (1852 m/h). It is standard in maritime and aviation navigation.
How to convert feet per second to knots
1 feet per second equals 0.5924838012958963 knot in this tool (via m/s):
1 fps = (0.3048 m/s ÷ 0.5144444444444445 m/s) knots = 0.5924838012958963 knots
Each feet per second carries 0.3048 m/s and each knot 0.5144444444444445 m/s, so one fps equals 0.3048 ÷ 0.5144444444444445 knots.
Let v(fps) be the numeric speed in Feet per Second (fps), and v(knots) in Knot (knots). Then:
v(knots) = v(fps) × (0.3048 / 0.5144444444444445)
Equivalently, divide by how many fps fit into one knots (m/s per knots divided by m/s per fps):
v(knots) = v(fps) ÷ 1.6878098571011957
Examples
Example #1: Convert 10 fps to knot
10 fps = 10 fps × (0.3048/0.5144444444444445) knots = 5.924838013 knots
10 fps = 10 fps ÷ 1.6878098571011957 = 5.924838013 knots
Example #2: Convert 50 fps to knot
50 fps = 50 fps × (0.3048/0.5144444444444445) knots = 29.6241900648 knots
50 fps = 50 fps ÷ 1.6878098571011957 = 29.6241900648 knots
Summary
To convert Feet per Second to Knot, multiply the value in fps by (0.3048 m/s per fps) / (0.5144444444444445 m/s per knots). Equivalently: value_knots = value_fps × (0.3048 / 0.5144444444444445). Numerically, 1 fps equals 0.5924838012958963 knots.
Relationship context
Both Feet per Second and Knot are expressed as fixed multiples of meters per second in this tool. Converting multiplies by the ratio of m/s per fps to m/s per knots, so results stay consistent with SI-based definitions (international mile, knot, feet, etc.).
