About Converting Cubic foot per Decades to Cubic inch per Years
Cubic foot per Decades and Cubic inch per Years 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 years = cubic foot per decades × 172.8
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per decades equals 8.973251e-11 base units, and 1 cubic inch per years equals 5.192854e-13 base units, so dividing one by the other gives the direct cubic foot per decades-to-cubic inch per years factor of 172.8.
Simple example
1 ft3/decade × 172.8 = 172.8 in3/yr
1 cubic foot per decades = 172.8 cubic inch per years.
Real-world example
60 ft3/decade × 172.8 = 10,368 in3/yr
60 cubic foot per decades = 10,368 cubic inch per years.

Frequently asked questions
How many cubic inch per years are in 1 cubic foot per decades?
1 cubic foot per decades equals 172.8 cubic inch per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per decades to cubic inch per years?
Multiply the cubic foot per decades value by 172.8. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per years back to cubic foot per decades?
Use the reverse factor: 1 cubic inch per years equals 0.005787037 cubic foot per decades. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per decades?
Cubic foot per Decades (ft3/decade) is a unit of flow rate.
What is a cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
Is the cubic foot per decades to cubic inch per years conversion exact?
Yes. Both cubic foot per decades and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 172.8 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.
