How to Convert Cubic inch/hour to Cubic meter/second

Converting Cubic inch/hour (in³/h) to Cubic meter/second (m³/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/hour equals 4.55196 × 10⁻⁹ Cubic meter/second, while 1 m³/s equals 2.196856 × 10⁸ 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:

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 (k_source):1 in³/h = 4.55196 × 10⁻⁹ cubic meter per second (m³/s)

2. Target SI Bridge (k_target):1 m³/s = 1 cubic meter per second (m³/s)

Step-by-step substitution for Cubic inch/hour → Cubic meter/second:V(m³/s) = V(in³/h) × ( 4.55196 × 10⁻⁹ / 1 ) = V(in³/h) × 4.55196 × 10⁻⁹

Worked Example

For an engineering input of 15 in³/h, applying the conversion factor yields exactly 6.82794 × 10⁻⁸ m³/s. At larger operational scale, 10000 Cubic inch/hour corresponds to 4.55196 × 10⁻⁵ m³/s.

Inverse check: 1 m³/s = 2.196856 × 10⁸ in³/h.
