About Converting Cubic foot per Hours to Cubic Kilometer per Years
Cubic foot per Hours and Cubic Kilometer 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 kilometer per years = cubic foot per hours × 2.482204e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per hours equals 0.00000786579072 base units, and 1 cubic kilometer per years equals 31.6887385068 base units, so dividing one by the other gives the direct cubic foot per hours-to-cubic kilometer per years factor of 2.482204e-7.
Simple example
1 ft3/h × 2.482204e-7 = 2.482204e-7 km3/yr
1 cubic foot per hours = 2.482204e-7 cubic kilometer per years.
Real-world example
60 ft3/h × 2.482204e-7 = 0.0000148932 km3/yr
60 cubic foot per hours = 0.0000148932 cubic kilometer per years.

Frequently asked questions
How many cubic kilometer per years are in 1 cubic foot per hours?
1 cubic foot per hours equals 2.482204e-7 cubic kilometer per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per hours to cubic kilometer per years?
Multiply the cubic foot per hours value by 2.482204e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per years back to cubic foot per hours?
Use the reverse factor: 1 cubic kilometer per years equals 4,028,678.061 cubic foot per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
What is a cubic kilometer per years?
Cubic Kilometer per Years (km3/yr) is a unit of flow rate.
Is the cubic foot per hours to cubic kilometer per years conversion exact?
Yes. Both cubic foot per hours and cubic kilometer per years are defined by fixed standards rather than physical artifacts, so the factor of 2.482204e-7 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.
