How to Convert Cubic foot/second to Cubic meter/hour

Converting Cubic foot/second (ft³/s) to Cubic meter/hour (m³/h) is a core calculation in Volumetric Flow Rate, which quantifies the volume of fluid passing through a designated conduit cross-section per unit of time. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Cubic foot/second equals 101.940648 Cubic meter/hour, while 1 m³/h equals 0.00980963 ft³/s.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (cubic meter per second (m³/s)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 ft³/s = 0.0283168 cubic meter per second (m³/s)

2. Target SI Bridge (k_target):1 m³/h = 0.000277778 cubic meter per second (m³/s)

Step-by-step substitution for Cubic foot/second → Cubic meter/hour:V(m³/h) = V(ft³/s) × ( 0.0283168 / 0.000277778 ) = V(ft³/s) × 101.940648

Mathematical FormulaValue in Cubic meter/hour = Value in Cubic foot/second × 101.94064773Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 8 ft³/s, applying the conversion factor yields exactly 815.525182 m³/h. At larger operational scale, 240 Cubic foot/second corresponds to 24465.755455 m³/h.

Inverse check: 1 m³/h = 0.00980963 ft³/s.
