About Converting Cubic Millimeter per Weeks to Gallon per Hours
Cubic Millimeter per Weeks and Gallon 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
gallon per hours = cubic millimeter per weeks × 1.572453e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per weeks equals 1.653439e-15 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic millimeter per weeks-to-gallon per hours factor of 1.572453e-9.
Simple example
1 mm3/wk × 1.572453e-9 = 1.572453e-9 gal/h
1 cubic millimeter per weeks = 1.572453e-9 gallon per hours.
Real-world example
60 mm3/wk × 1.572453e-9 = 9.434716e-8 gal/h
60 cubic millimeter per weeks = 9.434716e-8 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 cubic millimeter per weeks?
1 cubic millimeter per weeks equals 1.572453e-9 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per weeks to gallon per hours?
Multiply the cubic millimeter per weeks value by 1.572453e-9. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic millimeter per weeks?
Use the reverse factor: 1 gallon per hours equals 635,949,179.7 cubic millimeter per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per weeks?
Cubic Millimeter per Weeks (mm3/wk) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic millimeter per weeks to gallon per hours conversion exact?
Yes. Both cubic millimeter per weeks and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.572453e-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.
