How to Convert Gallon (US)/second to Cubic meter/day

Converting Gallon (US)/second (gal (US)/s) to Cubic meter/day (m³/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)/second equals 327.059578 Cubic meter/day, while 1 m³/d equals 0.00305755 gal (US)/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:

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)/s = 0.00378541 cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 m³/d = 1.157407 × 10⁻⁵ cubic meter per second (m³/s)
Step-by-step substitution for Gallon (US)/second → Cubic meter/day:V(m³/d) = V(gal (US)/s) × ( 0.00378541 / 1.157407 × 10⁻⁵ ) = V(gal (US)/s) × 327.059578

Worked Example

To convert 120 Gallon (US)/second (gal (US)/s) to Cubic meter/day (m³/d): multiply 120 by 327.059578 to get 39247.149377 m³/d. At an industrial engineering scale, 10000 gal (US)/s converts to 3270595.781376 m³/d.

Inverse check: 1 m³/d = 0.00305755 gal (US)/s.
