The ideal tool for travelers, students, and professionals for converting currencies and measurement units.

ConverterBox is a user-friendly universal unit converter with a twist: it provides reference definitions for every conversion unit.

What makes ConverterBox different:

— Instant results as you type: ConverterBox provides instant results as you type a new value. Most other unit converters only show you two units at a time and require you to go through too many steps before seeing the calculation results.

—Informative: Learn about each unit without opening an external app or a web browser and or the need to be online. Tap the question/info button next to the unit you want to learn about, and a description of that unit will pop up.

—Customizable: Add, remove, and sort units and categories according to your preference.

—Up-to-date currency exchange information — perfect for traveling, home, or office use. Stores the latest update, so you don't have to be online to calculate the exchange rates.

Categories include:
—SI system prefixes
—Computer data sizes
—Radix (numeral base)
—Many more are in the works for the upcoming updates!

—Numeral base (radix) conversions: Lets you convert between binary, decimal, hexadecimal, and 32 other numeral base systems! Supports every base from 2 (binary) to 36 (Hexatrigesimal) and fractions in each one of those systems!

With a list of over 300 units and definitions, this is the perfect tool for students, teachers, and professionals!

Best app out there

I got a recommendation from a friend about this app. It's well worth the money! I got a long list of possible conversions and the interface is very user friendly and clear. I been using other apps but this one is my winner. Thank you for a great product!
