Beginning with the Galaxy S8 series, Samsungs built-in calculator has improved by leaps and bounds.
The improved UI/UX is a given, but one of its newer essential features is its unit converter.
From the calculators main screen, tap on theruler icon,usually located in the middle of your screen.
With that said, as mentioned before, unit conversion is only available for relatively modern Samsung phones.
Unit Conversions for Older Samsung Galaxy Devices
Older Samsung phones dont have the unit conversion function.
However, you could use other methods that arent as quick, but still useful.
Rely on Google Search
When in doubt, trust Google search.
The most significant benefit of using Google search is its overall functionality.
You also dont have to download a new utility all you need is the internet.
The developers boast the apps user-friendliness for casual users.
To change the unit of measurement, simply select it from the categories and sub-categories menu options.
Another great app isClevCalc Calculator.
If you wish to get more conversion options, try using Google search or a third-party app.
