Quick Conversion Fact
1 cubic foot per second (ft³/s) = 215,438.96 pints per hour (pnt/h). This factor is exact for US liquid pints.
Understanding the Units
Cubic Foot Per Second (ft³/s)
A cubic foot per second measures how many cubic feet of fluid pass a point each second. One cubic foot equals 1,728 cubic inches or about 28.317 liters.
Pint Per Hour (pnt/h)
A pint per hour measures the volume flow in US liquid pints each hour. One US pint is 16 fluid ounces, or roughly 0.473 liter.
How the Conversion Works
Both units belong to the Volume Flow Rate measure, so they describe the same physical concept—how fast a volume moves. To convert, we translate the volume (cubic feet ↔ pints) and then adjust the time unit (seconds ↔ hours).
Step‑by‑step formula
- Convert cubic feet to pints: 1 ft³ = 59.84415584 pints.
- Convert seconds to hours: 1 second = 1⁄3,600 hour.
- Combine the two:
Thus, the single‑step factor is 59.84415584 × 3,600 ≈ 215,438.961 pints / hour per ft³ / second.
Worked Example
Convert 3 ft³/s to pints per hour.
- Multiply by the factor: 3 × 215,438.961 ≈ 646,316.883 pints/h.
- Round to two decimals for readability: 646,316.88 pnt/h.
So, a flow of 3 cubic feet per second equals roughly 646,317 pints per hour.
Practical Applications
- Water‑treatment plants: Engineers often need to express large inflows in pints per hour for dosing calculations.
- HVAC systems: Airflow rates may be measured in ft³/s, but maintenance logs sometimes use pints/h for liquid refrigerant flow.
- Irrigation design: Converting pump capacities helps match field‑level water delivery specs.
- Fuel‑distribution monitoring: Small‑scale fuel lines may be rated in pints/h, while larger pipelines use ft³/s.
Cubic Foot Per Second to Pint Per Hour Conversion Table
Each row applies the same rule: multiply cubic feet per second by 215,438.96 to obtain pints per hour.
