About Converting Gallon per Days to Cubic inches per Millisecond
Gallon per Days and Cubic inch per Millisecond 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 inches per millisecond = gallon per days × 0.00000267361111111
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 millisecond equals 0.016387064 base units, so dividing one by the other gives the direct gallon per days-to-cubic inch per millisecond factor of 0.00000267361111111.
Simple example
1 gal/d × 0.000002673611111 = 0.0000026736 in3/ms
1 gallon per days = 0.0000026736 cubic inches per millisecond.
Real-world example
60 gal/d × 0.000002673611111 = 0.0001604167 in3/ms
60 gallon per days = 0.0001604167 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 gallon per days?
1 gallon per days equals 0.0000026736 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cubic inch per millisecond?
Multiply the gallon per days value by 0.000002673611111. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to gallon per days?
Use the reverse factor: 1 cubic inch per millisecond equals 374,025.974 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 millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the gallon per days to cubic inch per millisecond conversion exact?
Yes. Both gallon per days and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000002673611111 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.
