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

Converting Liter/second (L/s) to Hundred-cubic foot/hour (100 ft³/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 Liter/second equals 1.271328 Hundred-cubic foot/hour, while 1 100 ft³/h equals 0.786579 L/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 L/s = 0.001 cubic meter per second (m³/s)

2. Target SI Bridge (k_target):1 100 ft³/h = 0.000786579 cubic meter per second (m³/s)

Step-by-step substitution for Liter/second → Hundred-cubic foot/hour:V(100 ft³/h) = V(L/s) × ( 0.001 / 0.000786579 ) = V(L/s) × 1.271328

Mathematical FormulaValue in Hundred-cubic foot/hour = Value in Liter/second × 1.271328Direct computational formula applied for standard conversion.

Worked Example

Converting 36 L/s yields an exact output of 45.767808 100 ft³/h in Hundred-cubic foot/hour. Under higher industrial throughput, 240 L/s translates to 305.11872 100 ft³/h.

Inverse check: 1 100 ft³/h = 0.786579 L/s.
