How to Convert Cubic inch/second to Liter/second

Converting Cubic inch/second (in³/s) to Liter/second (L/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 Cubic inch/second equals 0.0163871 Liter/second, while 1 L/s equals 61.023744 in³/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 in³/s = 1.638706 × 10⁻⁵ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/s = 0.001 cubic meter per second (m³/s)
Step-by-step substitution for Cubic inch/second → Liter/second:V(L/s) = V(in³/s) × ( 1.638706 × 10⁻⁵ / 0.001 ) = V(in³/s) × 0.0163871
Mathematical FormulaValue in Liter/second = Value in Cubic inch/second × 0.016387064Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 12 Cubic inch/second (in³/s) produces 0.196645 Liter/second (L/s). In heavy-duty utility and industrial workloads, 2500 in³/s equals 40.96766 L/s.

Inverse check: 1 L/s = 61.023744 in³/s.
