How to Convert Liter/minute to Cubic foot/hour

Converting Liter/minute (L/min) to Cubic foot/hour (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/minute equals 2.11888 Cubic foot/hour, while 1 ft³/h equals 0.471947 L/min.

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:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 L/min = 1.666667 × 10⁻⁵ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 ft³/h = 7.865791 × 10⁻⁶ cubic meter per second (m³/s)
Step-by-step substitution for Liter/minute → Cubic foot/hour:V(ft³/h) = V(L/min) × ( 1.666667 × 10⁻⁵ / 7.865791 × 10⁻⁶ ) = V(L/min) × 2.11888
Mathematical FormulaValue in Cubic foot/hour = Value in Liter/minute × 2.11888Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 L/min, applying the conversion factor yields exactly 31.7832 ft³/h. At larger operational scale, 480 Liter/minute corresponds to 1017.062402 ft³/h.

Inverse check: 1 ft³/h = 0.471947 L/min.
