About Converting Cubic Meter per Years to Cubic foot per Seconds
Cubic Meter per Years and Cubic foot 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 foot per seconds = cubic meter per years × 0.00000111907723919
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per years equals 3.168874e-8 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct cubic meter per years-to-cubic foot per seconds factor of 0.00000111907723919.
Simple example
1 m3/yr × 0.000001119077239 = 0.0000011191 ft3/s
1 cubic meter per years = 0.0000011191 cubic foot per seconds.
Real-world example
60 m3/yr × 0.000001119077239 = 0.0000671446 ft3/s
60 cubic meter per years = 0.0000671446 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 cubic meter per years?
1 cubic meter per years equals 0.0000011191 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per years to cubic foot per seconds?
Multiply the cubic meter per years value by 0.000001119077239. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to cubic meter per years?
Use the reverse factor: 1 cubic foot per seconds equals 893,593.3687 cubic meter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the cubic meter per years to cubic foot per seconds conversion exact?
Yes. Both cubic meter per years and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000001119077239 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.
