Flow Rate Unit Converter
Instantly convert between m³/h, GPM (US), and other Flow Rate units — accurate, free, and built for water treatment engineering work.
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) |
Engineering Context
Flow rate is the most frequently cross-referenced unit in water treatment procurement: US-manufactured pumps, membranes, and skids are almost always rated in GPM or MGD, while process design and P&IDs outside North America run in m³/h or L/s. Getting this conversion wrong is a common source of undersized equipment specs.

DCS vs. PLC in Water Treatment: Why Continuous Chemistry and Discrete Logic Need Different Control Architectures
A distributed control system and a programmable logic controller can both open the same valve, but they were built on opposite assumptions about what a plant is. Picking the wrong one for a zero-liquid-discharge evaporator or a scattered pump-station network doesn't show up on day one — it shows up years later, as downtime.

Stacked safety factors on pumps, blowers, membranes, and tanks don't just raise the purchase price — they push equipment out of its efficient operating window for years. A life-cycle model built on a real MBR retrofit shows a phased, right-sized design beating a one-time oversized build by roughly 10%, even when the deferred expansion eventually happens.
Read ArticleProduced Water Treatment: Why Direct Lithium Extraction Turns Zero Liquid Discharge From a Cost Center Into a Profit Center
Oilfield produced water has historically been a disposal problem solved by deep-well injection. As injection wells fill up and induced-seismicity restrictions tighten, the same brine is increasingly being read as a lithium ore body — but only if pretreatment is aggressive enough to protect an extraction bed that has zero tolerance for the oil and silica this water is full of.
