💡 Quick formula: LPH = LPM × 60 | LPM = LPH ÷ 60
LPM to LPH Formula
LPH = LPM × 60
LPM = LPH ÷ 60
Examples:
50 LPM = 3,000 LPH
200 LPM = 12,000 LPH
500 LPM = 30,000 LPH
Common Pump Flow Rates
| LPM | LPH | m³/hr | Use |
|---|---|---|---|
| 20 | 1,200 | 1.2 | Small domestic pump |
| 100 | 6,000 | 6.0 | Industrial process pump |
| 500 | 30,000 | 30.0 | Large cooling tower pump |
| 1,000 | 60,000 | 60.0 | High-capacity fire pump |
LPM is the standard unit in India for pump flow rates. LPH is commonly used for small dosing pumps and chemical feed systems.

LPM and LPH — When to Use Which
LPM (Litres per Minute) is the most common flow rate unit used in Indian industry for pumps, pipelines and water systems. Most pump datasheets, flow meters and piping standards in India list flow in LPM.
LPH (Litres per Hour) is used for slower flows — chemical dosing pumps, drip irrigation systems, boiler feed systems and any application where the flow rate is too small to express sensibly in LPM.
