What is this tool?

Unit conversion translates a quantity from one measurement system to another. This tool covers everyday categories with live updates and a swap control for reversing the from/to pair. Temperature uses proper °C/°F/K formulas rather than a simple scale factor.

How to use it

  1. Select a category (length, weight, temperature, etc.).
  2. Enter a value and choose from/to units.
  3. Copy the result or swap units to reverse the conversion.
