Methodology
For factor-based categories, values pass through the configured base unit: base value = input value × source factor, then output value = base value ÷ target factor.

Quick Reference Table
| Unit | Converted to m³/h | m³/h converted to unit |
|---|---|---|
| m³/d | 1 m³/d = 0.041667 m³/h | 1 m³/h = 24 m³/d |
| m³/min | 1 m³/min = 60 m³/h | 1 m³/h = 0.016667 m³/min |
| L/min | 1 L/min = 0.06 m³/h | 1 m³/h = 16.6667 L/min |
| L/s | 1 L/s = 3.6 m³/h | 1 m³/h = 0.277778 L/s |
| L/h | 1 L/h = 0.001 m³/h | 1 m³/h = 1000 L/h |
| GPM (US) | 1 GPM (US) = 0.227125 m³/h | 1 m³/h = 4.4029 GPM (US) |
| MGD (US) | 1 MGD (US) = 157.7255 m³/h | 1 m³/h = 0.00634013 MGD (US) |
01
Engineering Basis
Assumptions
- Convert only between units in the same physical quantity family and with the same declared concentration or operating basis.
Scope / Limitations
- The converter normalizes units; it does not validate source data, infer a process basis, or replace the assumptions of a downstream model.
02
Engineering Path
Upstream Context
- Declared value and source unit Use the unit stated on the sample record, supplier sheet, or design note.
Current Tool Decision
- Flow Rate Unit Converter Convert within this quantity family while preserving the declared engineering basis.
Downstream Engineering Step
- Plant Water & Mass Balance Use the normalized value in the relevant engineering calculation and verify its basis.
- Water Treatment Plant Hydraulic Profile Use the normalized value in the relevant engineering calculation and verify its basis.
- RO System Designer Use the normalized value in the relevant engineering calculation and verify its basis.
