Formula

Formula
ft³/hr = cfs × 3600

Multiply any value in cubic feet per second by 3600 to obtain the value in cubic feet per hour.

Worked example

Convert 10 cfs to ft³/hr.

  1. 01Start with 10 cfs.
  2. 02Multiply by the conversion factor: 10 × 3600 = 36000 ft³/hr.
Result10 cfs = 36000 ft³/hr

FAQ

What is the conversion factor from cfs to ft³/hr?
1 cfs equals 3600 ft³/hr. To convert, multiply the value in cubic feet per second by 3600.
How do I convert 1 cfs to ft³/hr?
1 cfs = 3600 ft³/hr. For any value, multiply by 3600.
How do I convert ft³/hr back to cfs?
Divide by the same factor — or equivalently, multiply by 0.0002777778. So 1 ft³/hr = 0.000277778 cfs.
When would I need to convert cubic foot per second to cubic foot per hour?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. cfs to ft³/hr is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
