About Converting Cubic foot per Years to Cubic inch per Seconds
Cubic foot per Years and Cubic inch per Seconds both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
cubic inch per seconds = cubic foot per years × 0.0000547581401398
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per years equals 8.973251e-10 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct cubic foot per years-to-cubic inch per seconds factor of 0.0000547581401398.
Simple example
1 ft3/yr × 0.00005475814014 = 0.0000547581 in3/s
1 cubic foot per years = 0.0000547581 cubic inch per seconds.
Real-world example
60 ft3/yr × 0.00005475814014 = 0.0032854884 in3/s
60 cubic foot per years = 0.0032854884 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 cubic foot per years?
1 cubic foot per years equals 0.0000547581 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per years to cubic inch per seconds?
Multiply the cubic foot per years value by 0.00005475814014. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to cubic foot per years?
Use the reverse factor: 1 cubic inch per seconds equals 18,262.125 cubic foot per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the cubic foot per years to cubic inch per seconds conversion exact?
Yes. Both cubic foot per years and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00005475814014 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
