Uconeer is a professional engineering unit conversion software package for Windows (See here for Mac support). It includes a wide range of technical measurement categories required by engineers, but it excludes the archaic and esoteric units that clutter the menus of other programs. However, if we have left out the particular measurement units that you do need you can add them in yourself, allowing you to work with those that are particular to your industry or location.
Purchase the Uconeer engineering unit converter together with our AioFlo Pipe Sizing Software and save $10 on a single user license. This gives you AioFlo for only $20. Bundle site licenses or enterprise licenses of Uconeer and AioFlo for even larger savings. See purchase page for full pricing details and links to place your order.
