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

Converting Gallon (US)/hour (gal (US)/h) to Liter/day (L/d) 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 (US)/hour equals 90.849883 Liter/day, while 1 L/d equals 0.0110072 gal (US)/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 gal (US)/h = 1.051503 × 10⁻⁶ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/d = 1.157407 × 10⁻⁸ cubic meter per second (m³/s)
Step-by-step substitution for Gallon (US)/hour → Liter/day:V(L/d) = V(gal (US)/h) × ( 1.051503 × 10⁻⁶ / 1.157407 × 10⁻⁸ ) = V(gal (US)/h) × 90.849883
Mathematical FormulaValue in Liter/day = Value in Gallon (US)/hour × 90.84988282Direct computational formula applied for standard conversion.
Worked Example

Converting 36 gal (US)/h yields an exact output of 3270.595781 L/d in Liter/day. Under higher industrial throughput, 10000 gal (US)/h translates to 908498.82816 L/d.

Inverse check: 1 L/d = 0.0110072 gal (US)/h.
