Engineering Unit Conversion app for iPhone and iPad

A comprehensive unit conversion tool specifically designed for engineers, scientists and students.

All the dimensions you need on a daily basis with all the units you commonly use.

Input negative values when required for temperatures, gauge pressures, etc.

Input values with exponents. Instead of typing in 1000000 you can use 1e6.

Input a value to be converted, select the unit you wish to convert from and immediately see the conversion to all the units within that dimension.

Remembers the last value and unit separately for each dimension.
