About This Tool
This tool converts flow rates between GPM and LPM using a two-field side-by-side interface suitable for engineers, technicians, and operators who need quick, exact conversions for pumps, piping, and process calculations.
Under the hood, the conversion uses 3.785411784 L per 1 GPM. Depending on the selected direction, the tool multiplies or divides by this factor and formats the result with fixed decimal precision.
Key value includes real-time results, consistent rounding, and handling of invalid inputs, which reduces errors in design reviews and reporting.
Use cases include pump sizing, flow-rate validation, HVAC system water management, and energy/water balance studies across facilities.
How to Use
1. Provide the numeric flow value in the input field.
2. Choose the source unit (GPM) and target unit (LPM) in the two dropdowns to set the conversion direction.
3. Observe the real-time converted value displayed in the opposite unit field.
4. Optionally adjust the decimal precision or input value to refine accuracy.
5. Apply the converted result to calculations, designs, or documentation.
