Product summary
Review the store description, core capabilities, and common use cases.
Stop unit prefix errors before they reach production.
Unit Prefix Sanity Checker scans any web page — datasheets, spec documents, BOMs, wiki articles — and highlights engineering values that look wrong. It catches the mistakes that spell-checkers can't: a millivolt where you meant a volt, a millifarad where you meant a microfarad, a megabit where you meant a megabyte.
133 detection rules across 11 engineering domains: electrical, frequency, data, length, mass, pressure, temperature, mechanical, chemical, radiation, and optical.
HOW IT WORKS
The engine reads the surrounding text to understand context, not just the number. "10 mF ceramic capacitor" gets flagged (probably means 10 µF). "10 mF supercapacitor" does not (millifarads are correct for supercaps). Every finding has a confidence score so you can focus on what matters.
Hover over any highlight to see what's wrong, why it was flagged, and a suggested fix. Click to copy the suggestion. Click a finding in the popup panel to jump straight to it on the page.
