Set default units per category
In Settings, you can choose a default unit for each category (for example, Meter for Length, Pascal for Pressure, Joule for Energy). The app remembers your preferences.

Copy results to clipboard
Tap a converted row to highlight it and copy the value with its unit (value + unit symbol) to the clipboard—quick and convenient for sharing or pasting into notes, messages, or calculations.
