Explanation

Formula: Liters per Second = Cubic Meters per Hour × 0.277778. Why: both units are normalized through liters per second, so the conversion combines fixed volume definitions with exact per-second, per-minute, or per-hour scaling.

Cubic Meters per Hour (m³/h): a common engineering flow unit used for plant equipment, air handling, and process system specifications.

Liters per Second (L/s): an SI-style volumetric flow unit used to express how many liters move each second.

This route is useful when moving between liter-scale and cubic-meter-scale SI flow reporting for process equipment, utilities, and engineering specifications.

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

Method & Reference
