Foot per Minute to Knot Converter
Speed · unit-converter
Convert Foot per Minute 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 Foot per Minute
Feet per minute is common for vertical speed in aviation and some HVAC airflow/velocity contexts.
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 minute to knots
1 foot per minute equals 0.009874730021598272 knot in this tool (via m/s):
1 fpm = (0.00508 m/s ÷ 0.5144444444444445 m/s) knots = 0.009874730021598272 knots
Each foot per minute carries 0.00508 m/s and each knot 0.5144444444444445 m/s, so one fpm equals 0.00508 ÷ 0.5144444444444445 knots.
Let v(fpm) be the numeric speed in Foot per Minute (fpm), and v(knots) in Knot (knots). Then:
v(knots) = v(fpm) × (0.00508 / 0.5144444444444445)
Equivalently, divide by how many fpm fit into one knots (m/s per knots divided by m/s per fpm):
v(knots) = v(fpm) ÷ 101.26859142607174
Examples
Example #1: Convert 10 fpm to knot
10 fpm = 10 fpm × (0.00508/0.5144444444444445) knots = 0.0987473002 knots
10 fpm = 10 fpm ÷ 101.26859142607174 = 0.0987473002 knots
Example #2: Convert 50 fpm to knot
50 fpm = 50 fpm × (0.00508/0.5144444444444445) knots = 0.4937365011 knots
50 fpm = 50 fpm ÷ 101.26859142607174 = 0.4937365011 knots
Summary
To convert Foot per Minute to Knot, multiply the value in fpm by (0.00508 m/s per fpm) / (0.5144444444444445 m/s per knots). Equivalently: value_knots = value_fpm × (0.00508 / 0.5144444444444445). Numerically, 1 fpm equals 0.009874730021598272 knots.
Relationship context
Both Foot per Minute and Knot are expressed as fixed multiples of meters per second in this tool. Converting multiplies by the ratio of m/s per fpm to m/s per knots, so results stay consistent with SI-based definitions (international mile, knot, feet, etc.).
