# Mobile applications for engineers

Applications are developed with extremely user-friendly interface so that the user could generate design models, obtain output data, define personal formulas and convert measurement units.

The program also enables you to convert measurement units for the following categories:

– Length

– Area

– Volume

– Pressure

– Force and mass

– Moment of force

– Angle

– Temperature

– Number.
