Instantly understand measurements and specs on any web page — hover to convert. Stop converting units in your head. Hover Measure shows you the conversion the instant you hover over any measurement on any web page — no clicks, no pop-ups, no copy-paste, no mental math. Just point at a number and read the answer. WHAT MAKES IT DIFFERENT Most converters only do "mm to inches." Hover Measure reads the context around a number, so it understands specs: • 140W on a charger → 28V @ 5A (USB-C PD 3.1 EPR) — the real charging profile • 20,000mAh → 20Ah — battery capacity, kept as capacity • 250×110mm → 9.84 × 4.33 in — whole dimension strings at once WORKS EVERYWHERE, ON EVERYTHING Amazon, AliExpress, eBay, spec sheets, recipes, articles, forums — if a page has a measurement, you can hover it. 60+ units across 12 categories: length, weight, volume, temperature, area, speed, pressure, power, energy, data, battery capacity, and USB-C Power Delivery. PRIVATE BY DESIGN Every conversion happens locally in your browser. No account, no sign-up, no analytics, no trackers — and nothing ever leaves your device. It's also carefully built inside its own shadow DOM, so it never interferes with a page's own layout or styles. MADE FOR PEOPLE WHO SHOP BY THE NUMBERS Electronics and chargers, makers and 3D printing, RC and drones, automotive and mechanics, tools, importers, engineers, and DIY — anyone comparing gear across international listings. YOUR CONTROLS • Adjustable precision (0–3 decimals) • Light, dark, or system theme • One-click on/off Free. Install it, browse normally, and hover anything.
