Full API documentation

Explanation

Formula: Cubic Meters per Second = Gallons per Minute (US) × 0.000063090196. Why: the route uses liters per second as the common basis, then applies the fixed US gallon definition together with the relevant per-minute or per-hour time scaling.

Gallons per Minute (US) (gpm): a US customary volumetric flow unit based on the US liquid gallon and commonly used in pumps, piping, and water systems.

Cubic Meters per Second (m³/s): a large SI volumetric flow unit used for high-capacity process, hydraulic, and infrastructure flow reporting.

This route is useful when translating between SI flow units and gallon- or cubic-foot-based reporting for pumps, piping, ventilation, and plant documentation.

This conversion is purely multiplicative because both units reduce through one liters-per-second flow basis with fixed unit-volume definitions and no offset.
