About Unit Converter Watch
This watch app converts units for length, temperature, weight/mass, volume, area, and speed with the convenience of the Apple Watch. Simply swipe left or right to see each section of the app. Tap one of the unit buttons on the top left to bring up a picker to change the units. Then tap the ‘X’ to close the picker view and enter the measurement you want to convert. It is that simple.
What’s new
Version 1.2 · Updated May 20, 2026
Improved conversion accuracy across length, mass, volume, area, speed, and temperature. Reworked the conversion engine so formulas are now based on consistent shared reference units. Fixed several incorrect or imprecise conversion formulas, including mass and area conversions. Added support for negative temperature entry. On the temperature screen, long-press the C± button to switch between positive and negative values.
