How to Convert Gallon (UK)/hour to Cubic centimeter/second

Converting Gallon (UK)/hour (gal (UK)/h) 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 (UK)/hour equals 1.262803 Cubic centimeter/second, while 1 cm³/s equals 0.791889 gal (UK)/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 gal (UK)/h = 1.262803 × 10⁻⁶ 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 (UK)/hour → Cubic centimeter/second:V(cm³/s) = V(gal (UK)/h) × ( 1.262803 × 10⁻⁶ / 1 × 10⁻⁶ ) = V(gal (UK)/h) × 1.262803

Mathematical FormulaValue in Cubic centimeter/second = Value in Gallon (UK)/hour × 1.26280278Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Gallon (UK)/hour (gal (UK)/h) to Cubic centimeter/second (cm³/s): multiply 50 by 1.262803 to get 63.140139 cm³/s. At an industrial engineering scale, 5000 gal (UK)/h converts to 6314.013889 cm³/s.

Inverse check: 1 cm³/s = 0.791889 gal (UK)/h.
