Foot per Minute to Inch per Second Converter
Speed · unit-converter
Convert Foot per Minute to Inch per Second 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 Inch per Second
Inches per second is used for small mechanical motion, machining feed rates, and vibration specs.
How to convert feet per minute to inches per second
1 foot per minute equals 0.2 inch per second in this tool (via m/s):
1 fpm = (0.00508 m/s ÷ 0.0254 m/s) ips = 0.2 ips
Each foot per minute carries 0.00508 m/s and each inch per second 0.0254 m/s, so one fpm equals 0.00508 ÷ 0.0254 ips.
Let v(fpm) be the numeric speed in Foot per Minute (fpm), and v(ips) in Inch per Second (ips). Then:
v(ips) = v(fpm) × (0.00508 / 0.0254)
Equivalently, divide by how many fpm fit into one ips (m/s per ips divided by m/s per fpm):
v(ips) = v(fpm) ÷ 4.999999999999999
Examples
Example #1: Convert 10 fpm to inch per second
10 fpm = 10 fpm × (0.00508/0.0254) ips = 2 ips
10 fpm = 10 fpm ÷ 4.999999999999999 = 2 ips
Example #2: Convert 50 fpm to inch per second
50 fpm = 50 fpm × (0.00508/0.0254) ips = 10 ips
50 fpm = 50 fpm ÷ 4.999999999999999 = 10 ips
Summary
To convert Foot per Minute to Inch per Second, multiply the value in fpm by (0.00508 m/s per fpm) / (0.0254 m/s per ips). Equivalently: value_ips = value_fpm × (0.00508 / 0.0254). Numerically, 1 fpm equals 0.2 ips.
Relationship context
Both Foot per Minute and Inch per Second 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 ips, so results stay consistent with SI-based definitions (international mile, knot, feet, etc.).
