UnitConv

This application converts between various units, generally SI and Imperial, but there are also some more specialised conversions, such as energy equivalents. Also included are some other converters, such as a bin/oct/hex/dec converter, a gas molecule speed calculator and an image size reckoner.

UnitConv is 26/32-bit neutral and should be compatible with all versions of RISC OS from 3 to 6.

UnitConv has been tested successfully on the Iyonix, the BeagleBoard, the PandaBoard, the IGEPv5 based RapidO Ig, and the iMX6.

You can download the UnitConv application (complete with in app help file, in html format) as a zip file.
