🚀 Introduction
In the world of chemical engineering, process safety, and fluid mechanics, flow rate plays a vital role in equipment design, pipeline sizing, and safety system calculations. However, engineers often encounter challenges when working with different unit systems — like converting from cubic meters per hour (m³/h) to gallons per minute (GPM) or liters per second (L/s).
To simplify this, we’ve created a free online Flow Rate Converter Tool — designed especially for engineers and technical professionals.

📐 What is Flow Rate?
Flow rate is the volume of fluid that passes through a point in a pipeline or system over a specific period of time. It’s a fundamental parameter in fluid mechanics and is usually expressed in:
- Cubic meters per hour (m³/h)
- Liters per second (L/s)
- Gallons per minute (GPM)
- Cubic feet per minute (CFM)
🔄 Why Use a Flow Rate Converter?
Engineers and designers often work across various systems, industries, and countries — each using different units. A quick, accurate converter can help in:
- 🌐 Converting international standards into your local working units
- 📊 Pipe sizing and pump selection
- 🛡️ Calculations in firewater systems or relief scenarios
- 🔬 Ensuring consistency in process safety studies
Explore our Pipe Flow Calculator to use converted values directly in pipe sizing.
📊 Common Flow Rate Units & Conversions
| Unit Name | Abbreviation | Equivalent in m³/h |
|---|---|---|
| Cubic meter/hour | m³/h | 1 m³/h = 1 m³/h |
| Liter/second | L/s | 1 L/s = 3.6 m³/h |
| Gallons/minute | GPM (US) | 1 GPM ≈ 0.2271 m³/h |
| Cubic feet/minute | CFM | 1 CFM ≈ 1.699 m³/h |
| Barrel/day | bbl/day | 1 bbl/day ≈ 0.0066 m³/h |
