How to Convert Hundred-cubic foot/hour to Liter/second

Converting Hundred-cubic foot/hour (100 ft³/h) to Liter/second (L/s) 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 Hundred-cubic foot/hour equals 0.786579 Liter/second, while 1 L/s equals 1.271328 100 ft³/h.

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):1 100 ft³/h = 0.000786579 cubic meter per second (m³/s)

2. Target SI Bridge (k_target):1 L/s = 0.001 cubic meter per second (m³/s)

Step-by-step substitution for Hundred-cubic foot/hour → Liter/second:V(L/s) = V(100 ft³/h) × ( 0.000786579 / 0.001 ) = V(100 ft³/h) × 0.786579

Mathematical FormulaValue in Liter/second = Value in Hundred-cubic foot/hour × 0.78657907Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Hundred-cubic foot/hour (100 ft³/h) to Liter/second (L/s): multiply 120 by 0.786579 to get 94.389489 L/s. At an industrial engineering scale, 100 100 ft³/h converts to 78.657907 L/s.

Inverse check: 1 L/s = 1.271328 100 ft³/h.
