How to Convert Gallon (US)/second to Cubic centimeter/second

Converting Gallon (US)/second (gal (US)/s) to Cubic centimeter/second (cm³/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 Gallon (US)/second equals 3785.411784 Cubic centimeter/second, while 1 cm³/s equals 0.000264172 gal (US)/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:

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 gal (US)/s = 0.00378541 cubic meter per second (m³/s)

2. Target SI Bridge (k_target):1 cm³/s = 1 × 10⁻⁶ cubic meter per second (m³/s)

Step-by-step substitution for Gallon (US)/second → Cubic centimeter/second:V(cm³/s) = V(gal (US)/s) × ( 0.00378541 / 1 × 10⁻⁶ ) = V(gal (US)/s) × 3785.411784

Mathematical FormulaValue in Cubic centimeter/second = Value in Gallon (US)/second × 3785.411784Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 36 gal (US)/s, applying the conversion factor yields exactly 136274.824224 cm³/s. At larger operational scale, 240 Gallon (US)/second corresponds to 908498.82816 cm³/s.

Inverse check: 1 cm³/s = 0.000264172 gal (US)/s.
