This app can convert UTM coordinates to a LOCAL DATUM, to WGS 84 and vice versa.
This means it does it's conversion in three way settings at one click.

It contains more than 500 datums of more than 70 countries e.g
United States
Nigeria
Algeria
Australia
Pakistan
India
Egypt
Poland
China
United Kingdom
Tunisia
Spain
Switzerland
Canada
Argentina
Brazil
Angola
Belgium
Bangladesh
Philippines
Israel
Bulgaria
Mexico
France
Cameroon
Botswana
Chile
Columbia
Croatia

And lots more.

CPROJ-WIZARD comes with default and customisation options to help you select datums of your choice in a given geography as a seperate conversion view.
This will help you carry out conversion for selected datums without fetching the datums again.
