About this app

Unit converter is the 6th set of Smart Tools® collection. This app includes Currency (money, Bitcoin) exchange rates.

There are a lot of unit converter calculator apps on the market. However, most are inconvenient and difficult to use because of poor and complicated UI.
This conversion app has intuitive and simple UI, that is designed for casual user like you. Trust me.

I've sorted essential unit sets for your daily life into 4 categories.

- Basic : length (distance), area, weight (mass), volume (capacity)
- Living : exchange rate, temperature, time, speed, shoes, clothing, hat, ring
- Science : pressure, force, work (energy), power, torque, flow, current, voltage, density, viscosity, concentration, astronomy
- Misc. : angle, data, fuel efficiency, cooking, illuminance, radiation, prefix, binary, time zone, blood sugar, hardness, AWG

It shows different unit sets depending on user's country. When you need more units, please send me an email at androidboy1@gmail.com.

I used to use it and liked it. It was quick and easy to use. But now when you open it the is an ad that acts like a video and it is loud. I couldn't find a "close" or a "skip" button so I had to "Close All". If the only way to use the app is to endure that loud ad then I its not for me. I understand that ads bring in revenue and am ok with ads that don't have sound but this is too loud. I don't watch news feed videos so I'm not about to listen to an ad. App has been deleted.

I'm sorry for making you uncomfortable. To make the ads mute, turn off [Sound Effect] at the settings.

I've had this app installed for a long time and figured I should rate it. I use it a couple times a day for all kinds of conversions, sometimes to convert currency before I make a purchase, sometimes just for amusement, sometimes to get an approximation in movies, documentaries, etc. Very user friendly and easy to use. Just input the known value and it automatically shows multiple conversions on-the-fly. An absolute necessity these days.

I've had this unit converter app for many YEARS. They recently added intrusive ads; it used to be small ads that didn't get in the way. Now, I get full-page, auto-playing, video ads that can't be skipped for 5+ seconds. The new ads completely block the screen and interrupt the entire process. 🙄😕 No thanks!!! I have installed a new unit converter app (no ads!) and I am uninstalling this app for good. Let me know if you ever remove the full page ads; I might come back and reinstall. 😉
