Converts US/Imperial units to SI/Metric on visible text only, rounding metric values to 2 decimals.
The Metric Converter userscript automatically converts US/Imperial units on webpages to SI/Metric units and appends the converted value in brackets behind the original US unit. All metric values are rounded to 2 decimal places for clean display. Ideal for shopping, cooking, recipes, and online research.
