How to Convert Gallon (UK)/second to Cubic meter/second

Converting Gallon (UK)/second (gal (UK)/s) 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 Gallon (UK)/second equals 0.00454609 Cubic meter/second, while 1 m³/s equals 219.969248 gal (UK)/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 (UK)/s = 0.00454609 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 Gallon (UK)/second → Cubic meter/second:V(m³/s) = V(gal (UK)/s) × ( 0.00454609 / 1 ) = V(gal (UK)/s) × 0.00454609

Mathematical FormulaValue in Cubic meter/second = Value in Gallon (UK)/second × 0.00454609Direct computational formula applied for standard conversion.

Worked Example

Converting 36 gal (UK)/s yields an exact output of 0.163659 m³/s in Cubic meter/second. Under higher industrial throughput, 100 gal (UK)/s translates to 0.454609 m³/s.

Inverse check: 1 m³/s = 219.969248 gal (UK)/s.
