Rainfall converter

Rainfall totals are easy to misread when forecast sources switch between metric and imperial reporting. One service may describe a storm in millimeters, while a local weather report uses inches of rain. This hub keeps rainfall conversion focused on that weather use case so you can compare totals, brief conditions, and read hydrology-style references without second-guessing what the number means.
