Quick answers for Unit Converter

Which categories of units can I convert?
Three tabs cover length (meters, feet, kilometers, miles, and more), weight, and temperature (Celsius, Fahrenheit, Kelvin), each with its own set of conversion pairs to pick from.
Does the result update as I type?
Yes, typing a number into the input field recalculates the converted value instantly, with no separate convert button to click.
Can I switch which units I am converting between?
Yes, each category shows a row of conversion pair tabs, like Meters to Feet or Celsius to Fahrenheit, and clicking a different pair swaps the active conversion.
Does my input leave the browser?
No. Conversions run locally. For percent math instead of units, use Percentage Calculator.
