How to Convert Liter/minute to Gallon (US)/hour

Converting Liter/minute (L/min) to Gallon (US)/hour (gal (US)/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 Liter/minute equals 15.850323 Gallon (US)/hour, while 1 gal (US)/h equals 0.0630902 L/min.

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 L/min = 1.666667 × 10⁻⁵ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 gal (US)/h = 1.051503 × 10⁻⁶ cubic meter per second (m³/s)
Step-by-step substitution for Liter/minute → Gallon (US)/hour:V(gal (US)/h) = V(L/min) × ( 1.666667 × 10⁻⁵ / 1.051503 × 10⁻⁶ ) = V(L/min) × 15.850323
Mathematical FormulaValue in Gallon (US)/hour = Value in Liter/minute × 15.85032314Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Liter/minute (L/min) to Gallon (US)/hour (gal (US)/h): multiply 120 by 15.850323 to get 1902.038777 gal (US)/h. At an industrial engineering scale, 5000 L/min converts to 79251.615707 gal (US)/h.

Inverse check: 1 gal (US)/h = 0.0630902 L/min.
