What Is the Flow Rate Converter?

Flow rate conversion standardizes fluid transport capacity across international hydraulic and piping standards.

How Does the Flow Rate Converter Work?

Converts through L/min: 1 GPM = 3.78541 L/min, 1 m³/h = 16.6667 L/min, 1 L/s = 60 L/min.

Flow Rate Converter Formula & Variables

The core mathematical equation utilized by this calculator is expressed as:

Q_{\text{target}} = Q_{\text{source}} \times \frac{\text{Factor}_{\text{source}}}{\text{Factor}_{\text{target}}}

Converts through the standard unit Liters per minute (1 GPM ≈ 3.78541 L/min).

How to Use the Flow Rate Converter

  1. Enter pump or pipe flow volume and select current and desired units.

Step-by-Step Example Calculation
