A unit converter changes a measurement from one unit into another, like miles to kilometers or Celsius to Fahrenheit. YaliKit covers more than 150 units across 18 categories, from length and weight to temperature, volume, speed, and data, updating instantly as you type. Every calculation runs locally in your browser with plain math, so it works offline and stays private.

Pro Tips
Use the Common Chips
Each category has a row of common conversions like cm to in or km to mi. Tap one to set both units at once instead of scrolling two dropdowns.
Temperature Is Not a Ratio
Celsius, Fahrenheit, Kelvin and Rankine each have a different zero point, so conversions use offset formulas, not a single multiplier. The tool handles this for you.
Watch the Rate Line
The line under the result shows the exact rate both ways, for example 1 mi = 1.609344 km. It is a quick sanity check and a handy reference to copy.
