About Converting Gallon per Weeks to Cubic inch per Hours
Gallon per Weeks and Cubic inch 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 inch per hours = gallon per weeks × 1.375
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 cubic inch per hours equals 4.551962e-9 base units, so dividing one by the other gives the direct gallon per weeks-to-cubic inch per hours factor of 1.375.
Simple example
1 gal/wk × 1.375 = 1.375 in3/h
1 gallon per weeks = 1.375 cubic inch per hours.
Real-world example
60 gal/wk × 1.375 = 82.5 in3/h
60 gallon per weeks = 82.5 cubic inch per hours.

Frequently asked questions
How many cubic inch per hours are in 1 gallon per weeks?
1 gallon per weeks equals 1.375 cubic inch per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per weeks to cubic inch per hours?
Multiply the gallon per weeks value by 1.375. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per hours back to gallon per weeks?
Use the reverse factor: 1 cubic inch per hours equals 0.7272727273 gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
Is the gallon per weeks to cubic inch per hours conversion exact?
Yes. Both gallon per weeks and cubic inch per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.375 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.
