Formula

Formula
L/hr = ft³/min × 1699.011

Multiply any value in cubic feet per minute by 1699.011 to obtain the value in litres per hour.

Worked example

Convert 1 ft³/min to L/hr.

  1. 01Start with 1 ft³/min.
  2. 02Multiply by the conversion factor: 1 × 1699.011 = 1699.01 L/hr.
Result1 ft³/min = 1699.01 L/hr

FAQ

What is the conversion factor from ft³/min to L/hr?
1 ft³/min equals 1699.011 L/hr. To convert, multiply the value in cubic feet per minute by 1699.011.
How do I convert 1 ft³/min to L/hr?
1 ft³/min = 1699.01 L/hr. For any value, multiply by 1699.011.
How do I convert L/hr back to ft³/min?
Divide by the same factor — or equivalently, multiply by 0.0005885778. So 1 L/hr = 0.000588578 ft³/min.
When would I need to convert cubic foot per minute to litre 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. ft³/min to L/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).
