About Converting Cubic foot per Seconds to Imperial pints per Millisecond
Cubic foot per Seconds and Imperial pint 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
imperial pints per millisecond = cubic foot per seconds × 0.0498306836723
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 imperial pint per millisecond equals 0.56826125 base units, so dividing one by the other gives the direct cubic foot per seconds-to-imperial pint per millisecond factor of 0.0498306836723.
Simple example
1 ft3/s × 0.04983068367 = 0.0498306837 imp pt/ms
1 cubic foot per seconds = 0.0498306837 imperial pints per millisecond.
Real-world example
60 ft3/s × 0.04983068367 = 2.98984102 imp pt/ms
60 cubic foot per seconds = 2.98984102 imperial pints per millisecond.

Frequently asked questions
How many imperial pints per millisecond are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 0.0498306837 imperial pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to imperial pint per millisecond?
Multiply the cubic foot per seconds value by 0.04983068367. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per millisecond back to cubic foot per seconds?
Use the reverse factor: 1 imperial pint per millisecond equals 20.06795665 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
What is a imperial pint per millisecond?
Imperial pint per Millisecond (imp pt/ms) is a unit of flow rate.
Is the cubic foot per seconds to imperial pint per millisecond conversion exact?
Yes. Both cubic foot per seconds and imperial pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.04983068367 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
