Software for RISC OS

Unit convert logo

by Chris Johnson



(Version 2.36, 21 Feb 2017)

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.
