How to Convert Cubic foot/minute to Liter/day

Converting Cubic foot/minute (ft³/min) to Liter/day (L/d) 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/minute equals 40776.259092 Liter/day, while 1 L/d equals 2.452407 × 10⁻⁵ ft³/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 ft³/min = 0.000471947 cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/d = 1.157407 × 10⁻⁸ cubic meter per second (m³/s)
Step-by-step substitution for Cubic foot/minute → Liter/day:V(L/d) = V(ft³/min) × ( 0.000471947 / 1.157407 × 10⁻⁸ ) = V(ft³/min) × 40776.259092
Mathematical FormulaValue in Liter/day = Value in Cubic foot/minute × 40776.25909248Direct computational formula applied for standard conversion.
Worked Example

Converting 36 ft³/min yields an exact output of 1467945.327329 L/d in Liter/day. Under higher industrial throughput, 1000 ft³/min translates to 4.077626 × 10⁷ L/d.

Inverse check: 1 L/d = 2.452407 × 10⁻⁵ ft³/min.
