I developed unitMeasure, because I couldn't find an app that had an intuitive design, ability to view all the results in one take, work offline, and be lightweight. This app matches everything that I have ever needed within a unit converter and will fit your needs as well.
For more information and policies about the app, you can have a look: https://www.unitmeasure.xyz
The app is available in English, Dutch, Spanish, and German
