This is a comprehensive engineering unit converter with an intuitive spinning wheel interface. There is no add, no hidden code, no need for a network connection, and the total size is about half a megabyte.

Choose a category such as length, energy, entropy, electric charge, etc., from a list. The available units appear in two spinning wheels. Spin the wheels to select 'From Unit' and 'To Unit'. That is it. You can change the input value in the yellow field, sort units, or use the swap button. Additional info about a measure is displayed when the help button is pressed.

Currently there are 50 measures with more than 500 units. Try the radix conversion, or calculate a mortgage payment, convert length with compound unit such as 5 ft 9 inches, or coordinate transformation from lat long to UTM.

If you find a particular measure or unit is missing, just write to us. We will update the converter in no time. If you like the converter, we hope you will upgrade to the affordable Engineering Converter Plus to support the project. In the Plus version you can create your own measure, or add new units to a built-in measures, create your favorite list, and the converter will keep track of the measures you use most (in the frequent 10 tab). Thanks!

Version 6.01: A few little improvements after the major update of 6.0, which took customization to a new level. In the Plus version now you can add any custom unit to a built-in measure or add your own custom measure. Deleting unwanted units also have been made more intuitive.
