How it works
- Converted value = × f₁ / f₂
- 1 m³/h = 1,000/60 L/min; 1 US gal = 3.785411784 L; 1 Imp gal = 4.54609 L

Assumptions and limitations
This is volumetric flow, not mass flow. US and Imperial gallons are different units. Negative values can represent reverse flow. It does not model pressure losses or pipe capacity. Example: 60 L/min = 1 L/s = 3.6 m³/h.
