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

Converting Liter/day (L/d) 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/day equals 0.0110072 Gallon (US)/hour, while 1 gal (US)/h equals 90.849883 L/d.

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/d = 1.157407 × 10⁻⁸ 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/day → Gallon (US)/hour:V(gal (US)/h) = V(L/d) × ( 1.157407 × 10⁻⁸ / 1.051503 × 10⁻⁶ ) = V(L/d) × 0.0110072
Mathematical FormulaValue in Gallon (US)/hour = Value in Liter/day × 0.011007169Direct computational formula applied for standard conversion.
Worked Example

To convert 2.5 Liter/day (L/d) to Gallon (US)/hour (gal (US)/h): multiply 2.5 by 0.0110072 to get 0.0275179 gal (US)/h. At an industrial engineering scale, 1000 L/d converts to 11.007169 gal (US)/h.

Inverse check: 1 gal (US)/h = 90.849883 L/d.
