About Converting Cubic inch per Hours to Quarts per Millisecond
Cubic inch per Hours and 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
quarts per millisecond = cubic inch per hours × 4.810005e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct cubic inch per hours-to-quart per millisecond factor of 4.810005e-9.
Simple example
1 in3/h × 4.810005e-9 = 4.810005e-9 qt/ms
1 cubic inch per hours = 4.810005e-9 quarts per millisecond.
Real-world example
60 in3/h × 4.810005e-9 = 2.886003e-7 qt/ms
60 cubic inch per hours = 2.886003e-7 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 cubic inch per hours?
1 cubic inch per hours equals 4.810005e-9 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to quart per millisecond?
Multiply the cubic inch per hours value by 4.810005e-9. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to cubic inch per hours?
Use the reverse factor: 1 quart per millisecond equals 207,900,000 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the cubic inch per hours to quart per millisecond conversion exact?
Yes. Both cubic inch per hours and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.810005e-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.
