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

Converting Cubic meter/hour (m³/h) to Gallon (UK)/hour (gal (UK)/h) 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 meter/hour equals 219.969248 Gallon (UK)/hour, while 1 gal (UK)/h equals 0.00454609 m³/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:

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 m³/h = 0.000277778 cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 gal (UK)/h = 1.262803 × 10⁻⁶ cubic meter per second (m³/s)
Step-by-step substitution for Cubic meter/hour → Gallon (UK)/hour:V(gal (UK)/h) = V(m³/h) × ( 0.000277778 / 1.262803 × 10⁻⁶ ) = V(m³/h) × 219.969248
Mathematical FormulaValue in Gallon (UK)/hour = Value in Cubic meter/hour × 219.9692483Direct computational formula applied for standard conversion.
Worked Example

To convert 50 Cubic meter/hour (m³/h) to Gallon (UK)/hour (gal (UK)/h): multiply 50 by 219.969248 to get 10998.462415 gal (UK)/h. At an industrial engineering scale, 5000 m³/h converts to 1099846.241495 gal (UK)/h.

Inverse check: 1 gal (UK)/h = 0.00454609 m³/h.
