About Converting Cubic inch per Years to Cubic Meter per Hours
Cubic inch per Years and Cubic Meter per Hours 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 meter per hours = cubic inch per years × 1.869427e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per years equals 5.192854e-13 base units, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct cubic inch per years-to-cubic meter per hours factor of 1.869427e-9.
Simple example
1 in3/yr × 1.869427e-9 = 1.869427e-9 m3/h
1 cubic inch per years = 1.869427e-9 cubic meter per hours.
Real-world example
60 in3/yr × 1.869427e-9 = 1.121656e-7 m3/h
60 cubic inch per years = 1.121656e-7 cubic meter per hours.

Understanding the Cubic Meter per Hours
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Where it's used: Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
Uses of the Cubic Meter per Hours today
- HVAC equipment airflow and liquid-flow ratings
- Industrial pump and system flow specifications
- Building ventilation system design

Frequently asked questions
How many cubic meter per hours are in 1 cubic inch per years?
1 cubic inch per years equals 1.869427e-9 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per years to cubic meter per hours?
Multiply the cubic inch per years value by 1.869427e-9. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to cubic inch per years?
Use the reverse factor: 1 cubic meter per hours equals 534,923,156.5 cubic inch per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Is the cubic inch per years to cubic meter per hours conversion exact?
Yes. Both cubic inch per years and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.869427e-9 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.
