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

There are a lot of unit conversion apps on the market. However, most are inconvenient and difficult to use because of poor and complicated UI.
This 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. [email protected]
