Volumetric Flow Rate Converter

What is Volumetric Flow Rate?

Volumetric Flow Rate measures the volume of fluid passing through a surface per unit of time.

It is a key parameter in engineering, fluid dynamics, HVAC, and process industries.

The SI unit is cubic meters per second (m³/s).

 

Why Use a Volumetric Flow Rate Converter?

• Instantly convert between L/s, m³/s, GPM, and CFM.
• Useful for fluid mechanics, hydraulics, and HVAC calculations.
• Perfect for engineers, technicians, and students.

 

 Common Use Cases

• Hydraulic systems – Pump and pipeline flow measurements.

 FAQs

1. What is the SI unit of volumetric flow rate?

The SI unit is cubic meters per second (m³/s).

2. What’s the difference between CFM and L/s?

CFM = cubic feet per minute (common in HVAC).

L/s = liters per second (metric system).

3. How do you measure volumetric flow rate?

Using flow meters (venturi meters, orifice plates, rotameters, etc.).

4. Can I convert GPM to m³/h?

Yes – 1 US GPM ≈ 0.227 m³/h.

5. Is this tool free?

Yes – completely free online converter.
