About Converting Cubic inch per Seconds to Imperial quarts per Millisecond
Cubic inch per Seconds and Imperial quart 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
imperial quarts per millisecond = cubic inch per seconds × 0.0000144186005996
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct cubic inch per seconds-to-imperial quart per millisecond factor of 0.0000144186005996.
Simple example
1 in3/s × 0.0000144186006 = 0.0000144186 imp qt/ms
1 cubic inch per seconds = 0.0000144186 imperial quarts per millisecond.
Real-world example
60 in3/s × 0.0000144186006 = 0.000865116 imp qt/ms
60 cubic inch per seconds = 0.000865116 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 0.0000144186 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to imperial quart per millisecond?
Multiply the cubic inch per seconds value by 0.0000144186006. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to cubic inch per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 69,354.8582 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the cubic inch per seconds to imperial quart per millisecond conversion exact?
Yes. Both cubic inch per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0000144186006 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.
