Why this tool is useful
Use this converter when specifications, downloads or measurements are given in US gallons per minute, but your worksheet or destination requires liters per second. It avoids manual factor mistakes.

Us Gallons Per Minute to Liters Per Second Converter
Convert US gallons per minute (gpm) to liters per second (L/s) with a transparent flow rate formula.
Ready. Your working data stays in this browser.
How it works
The browser converts gpm to the shared flow rate base unit using scale 0.0630902 and offset 0, then converts that base value to L/s using scale 1 and offset 0.
Practical example
For example, entering 1 gpm returns 0.0630901964 L/s. Results include the formula and enough precision for a quick verification.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
