Instant LBS to KG Converter

Instantly converts weights in pounds (lbs) to kilograms (kg) as you browse. Detected values are highlighted with a subtle dotted underline, and hovering shows the original and converted units in a tooltip.

Changelog (v1.1.0)

New: range support — converts “35–65 pounds”, “35-65 lbs”, “35 to 65 lb”.

New: glassmorphism tooltip with smooth scale/fade animation.

Smarter: skips conversion when kg is already shown nearby.

Smarter: catches common variants/typos (lb, lbs, pounds, pund, bls).

Performance: lightweight hybrid auto-update (click/scroll + throttled observer) converts newly revealed content without slowing pages.

Internationalization: tooltips localized (EN, PT-BR, ES, FR, DE, IT, JA, ZH-CN, RU, KO).
