How to Convert Cubic inch/hour to Liter/day

Converting Cubic inch/hour (in³/h) 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 inch/hour equals 0.393289 Liter/day, while 1 L/d equals 2.542657 in³/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 in³/h = 4.55196 × 10⁻⁹ 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 inch/hour → Liter/day:V(L/d) = V(in³/h) × ( 4.55196 × 10⁻⁹ / 1.157407 × 10⁻⁸ ) = V(in³/h) × 0.393289
Mathematical FormulaValue in Liter/day = Value in Cubic inch/hour × 0.39328932Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 50 Cubic inch/hour (in³/h) produces 19.664466 Liter/day (L/d). In heavy-duty utility and industrial workloads, 240 in³/h equals 94.389437 L/d.

Inverse check: 1 L/d = 2.542657 in³/h.
