How to Convert Liter/hour to Cubic foot/hour

Converting Liter/hour (L/h) 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/hour equals 0.0353147 Cubic foot/hour, while 1 ft³/h equals 28.316847 L/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:

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/h = 2.777778 × 10⁻⁷ 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/hour → Cubic foot/hour:V(ft³/h) = V(L/h) × ( 2.777778 × 10⁻⁷ / 7.865791 × 10⁻⁶ ) = V(L/h) × 0.0353147
Mathematical FormulaValue in Cubic foot/hour = Value in Liter/hour × 0.035314667Direct computational formula applied for standard conversion.
Worked Example

Converting 250 L/h yields an exact output of 8.828667 ft³/h in Cubic foot/hour. Under higher industrial throughput, 10000 L/h translates to 353.146667 ft³/h.

Inverse check: 1 ft³/h = 28.316847 L/h.
