About Converting Gallon per Days to Cubic inch per Weeks
Gallon per Days and Cubic inch per Weeks 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 weeks = gallon per days × 1617
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 cubic inch per weeks equals 2.709501e-11 base units, so dividing one by the other gives the direct gallon per days-to-cubic inch per weeks factor of 1617.
Simple example
1 gal/d × 1617 = 1,617 in3/wk
1 gallon per days = 1,617 cubic inch per weeks.
Real-world example
60 gal/d × 1617 = 97,020 in3/wk
60 gallon per days = 97,020 cubic inch per weeks.

Frequently asked questions
How many cubic inch per weeks are in 1 gallon per days?
1 gallon per days equals 1,617 cubic inch per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cubic inch per weeks?
Multiply the gallon per days value by 1617. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per weeks back to gallon per days?
Use the reverse factor: 1 cubic inch per weeks equals 0.0006184292 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
Is the gallon per days to cubic inch per weeks conversion exact?
Yes. Both gallon per days and cubic inch per weeks are defined by fixed standards rather than physical artifacts, so the factor of 1617 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.
