Customizable multi-function calculator and converter tool

Remember when NASA lost like billions of dollars because they forgot to convert from metric to imperial? Don't let this happen to you! CoreWillSoft's UseTool | Converter&Calculator app is your one-stop shop for all your unit conversion needs.

Whether it's temperature, length, power, or area, this app's got you covered. Specialty conversation like fuel consumption and android-specific metrics make this tool a cut above the rest. The design is intuitive to use and actually a rather fetching teal by default - you can change this to your liking, though, plus tweak the font style and background as you please.

The app auto-saves your calculation history, making it easy to see what work you've already done. It's supported by both smartphones and tablets.

CoreWillSoft's UseTool | Converter&Calculator is a useful app to keep handy in your e-toolbelt.

Developer's original description available here
UseTool combines converter and calculator in one app and lets you customise the interface by your own taste. We tried to pick for you the most frequently converted values such as currency, temperature, length, area, power, time, volume, mass, angle, area, data, speed, pressure, energy, flow, luminance, force etc. and some nice features like fuel consumption, kitchen, design and android specific metrics for people who don't like to switch between different apps to find an appropriate conversion.


- integrates converter and calculator in one cohesive app,
- interface customisation (color, font style, background),
- saves your calculation history and conversion preferences,
- common and specific values for conversion
- usable 7 and 10 inches tablet design

Try it and give your feedback, we will try our best to support you and to accustom the app for your needs!

    The "leatherman/gerber" all-in-one utility kit for every conversions or calculations need. Compact and lightweight yet packed with so many tools I am shocked this app is free!
