inch per second to foot per second
Convert inch per second (in/s) to foot per second (ft/s). Use an editable speed converter, conversion formula, and reference table.
1 in/s = 0.08333333333 ft/s
Conversion formula
One inch per second equals 0.08333333333 foot per second. Multiply your value in inch per second by this factor to get foot per second. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 inch per second:5 × 0.08333333333 = 0.4166666667 ft/s

About these measurements
Speed is distance traveled per unit of time.
The base reference used here is the meter per second. One inch per second is 0.0254 base units; one foot per second is 0.3048 base units.
Important distinctions
Mach is excluded because the speed of sound depends on medium and temperature.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
