Reference: 1 L/s ≈ 60 L/min ≈ 3.6 m³/h ≈ 15.8503 GPM ≈ 0.0353147 CFS
Liquid flow rates define how fast a fluid moves through a pipe or system — affecting performance, safety, and efficiency in industries like plumbing, agriculture, irrigation, medical equipment, HVAC systems, oil & gas, and environmental science.
But around the world, flow rates are measured in different units:
L/min – Liters per minute
L/sec – Liters per second
m³/hr – Cubic meters per hour
GPM – Gallons per minute (US)
GPH – Gallons per hour (US)
Barrels per day (BPD) – Oil industry
CFS – Cubic feet per second (hydrology)
The Free Liquid Flow Rate Converter by AlllinTools makes these variations easy to understand.
Enter any flow measurement → instantly convert to your chosen unit → apply confidently in real life.
Precision in flow measurement keeps systems running smoothly.
Flow rate measures volume per unit of time:
Flow Rate = Volume / Time
Imagine filling a bottle:
Fast flow → bottle fills quickly
Slow flow → bottle takes time
In engineering terms:
✔ Higher flow = faster delivery
✔ Lower flow = controlled supply
Correct flow ensures:
Enough water reaches every part of a house
Irrigation supports crops correctly
Engines and pumps avoid overheating
Hospitals deliver fluids or oxygen safely
Oil pipelines operate efficiently
Flow matters every day — whether we notice it or not.
Different industries require different units.
Misinterpretation causes:
❌ Pump failure
❌ Under-/over-watering crops
❌ Poor cooling in HVAC systems
❌ Medical emergency risks
❌ Energy waste
❌ Water supply inconsistency
Conversion makes data usable globally — avoiding expensive mistakes.
| Unit | Full Form | Common Use |
|---|---|---|
| L/min | Liters per minute | Domestic water systems |
| L/sec | Liters per second | Industrial & firefighting |
| m³/hr | Cubic meters per hour | Large systems, pipelines |
| GPM | Gallons per minute | HVAC, plumbing (US) |
| GPH | Gallons per hour | Small pumps, beverage systems |
| BPD | Barrels per day | Oil & gas transport |
| CFS | Cubic feet per second | River flow measurement |
AlllinTools combines household and industrial units into one convenient converter.
Example equivalents:
1 m³/hr = 16.6667 L/min
1 GPM = 3.78541 L/min
1 L/sec = 60 L/min
1 BPD ≈ 0.02817 m³/hr
Sample conversion:
Flow: 5 GPM
→ 5 × 3.78541 = 18.93 L/min
Precision → Prevents operational failure.
🏠 Home Water Supply
Shower flow rate = 10 L/min
→ Ensure good pressure and comfort
🚜 Agriculture & Irrigation
Sprinkler needs 2 m³/hr
→ Pump rating shows GPM → convert clearly
🏭 Industrial Manufacturing
Ensure lubrication and coolant flow meets machine requirements
💉 Medical Devices
Precise flow ensures safe infusion of medications and IV fluids
🌬️ HVAC & Refrigeration
Flow controls cooling efficiency and energy consumption
🌊 Environmental Science
River discharge measured in CFS → compare globally
Flow = the heartbeat of many systems.
| L/min | GPM | Use Case |
|---|---|---|
| 4 | 1.06 | Low-flow sink |
| 9 | 2.38 | Standard shower head |
| 20 | 5.28 | Commercial faucet |
| 60 | 15.85 | Fire hose supply |
| 180 | 47.55 | Industrial pump |
