Unit Conversion for Safari

Smart Unit Converter for Safari automatically detects measurements on web pages and converts them instantly while you browse. When reading international websites, you often see unfamiliar units such as Fahrenheit, miles, inches, pounds, or gallons. This extension detects those values directly on the page and displays the converted result next to them so you can understand measurements immediately. Unlike traditional unit converter apps, Smart Unit Converter works directly inside Safari. You do not need to copy values or search for conversions. Everything appears automatically while you browse. The extension supports bidirectional conversion between metric and imperial units. Whether a page uses Fahrenheit or Celsius, miles or kilometers, pounds or kilograms, both units are displayed so you can instantly understand the measurement.
