How to Convert Liter/second to Cubic inch/second

Converting Liter/second (L/s) to Cubic inch/second (in³/s) 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 61.023744 Cubic inch/second, while 1 in³/s equals 0.0163871 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:

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/s = 0.001 cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 in³/s = 1.638706 × 10⁻⁵ cubic meter per second (m³/s)
Step-by-step substitution for Liter/second → Cubic inch/second:V(in³/s) = V(L/s) × ( 0.001 / 1.638706 × 10⁻⁵ ) = V(L/s) × 61.023744
Mathematical FormulaValue in Cubic inch/second = Value in Liter/second × 61.02374409Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 L/s, applying the conversion factor yields exactly 2196.854787 in³/s. At larger operational scale, 2500 Liter/second corresponds to 152559.360237 in³/s.

Inverse check: 1 in³/s = 0.0163871 L/s.
