Amazon Imperial to Metric

Instantly convert imperial measurements to metric on Amazon product pages. Amazon Imperial to Metric automatically detects feet, inches, and dimension formats on Amazon product listings and displays the metric equivalents (meters, centimeters) right next to the original measurements. No more mental math or switching to a calculator. FEATURES: • Converts feet, inches, and combined feet+inches to meters/centimeters • Handles 2D and 3D dimension formats (e.g., 10 x 5 x 2 inches) • Supports fractional measurements (e.g., 5' 3 1/2") • Clean inline display with subtle green text • Simple on/off toggle in the popup • Lightweight with zero performance impact PRIVACY FIRST: • No data is collected or transmitted — ever • No data is stored locally on your device • No analytics, no tracking, no accounts • All conversions happen locally in your browser • The only stored data is your on/off preference via Chrome's built-in sync • Fully open source — review every line of code on GitHub OPEN SOURCE: This extension is fully open source and community-driven. The complete source code is available at: https://github.com/danielgomezrico/chrome-amazon-metrics-system-extension Report bugs or request features on GitHub. Contributions are welcome. HOW IT WORKS: The extension scans Amazon product pages for imperial measurements and appends the metric conversion in parentheses. It uses a MutationObserver to handle dynamically loaded content, so conversions appear even as Amazon loads additional product details.
