Understanding Cubic Foot Per Hour and Pint Per Hour

Both units belong to the volume flow rate family. A cubic foot per hour (ft³/h) measures how many cubic feet of fluid pass a point each hour. A pint per hour (pnt/h) does the same using U.S. liquid pints. Knowing how to switch between them helps engineers, plumbers, and hobbyists speak the same language.

Exact conversion factor

The internationally accepted relationship is:

1 ft³/h = 59.8441 pnt/h

This factor comes from the volume equivalence 1 ft³ = 28.316846592 L and 1 U.S. liquid pint = 0.473176473 L.

Conversion formula

To convert any flow rate from cubic feet per hour to pints per hour, multiply by the factor:

pnt/h = ft³/h × 59.8441

Worked example

Suppose a small pump delivers 15 ft³/h. Applying the formula:

1. 15 ft³/h × 59.8441 = 897.6615 pnt/h

The pump’s output is therefore about 898 pint per hour (rounded to the nearest whole pint).

Practical Applications of This Conversion

• HVAC design: Air‑handling units are often rated in ft³/h, but maintenance logs may use pints for liquid refrigerant flow.
• Plumbing and irrigation: Contractors calculate water‑delivery rates in ft³/h, yet local codes sometimes specify limits in pints per hour.
• Brewing and food processing: Large kettles are sized in cubic feet, while ingredient dosing is tracked in pints.
• Laboratory equipment: Peristaltic pumps may be labeled in ft³/h, but experimental protocols often require pints per hour for reagent addition.

Each row applies the same rule: multiply cubic feet per hour by 59.8441.

Key Takeaways

Switching between cubic feet per hour and pints per hour is a simple multiplication by 59.8441. Whether you’re sizing a pump, checking a code compliance sheet, or scaling a recipe, the formula and table give you instant, reliable results.
