Conversion Table for US GPA to UK class degrees
US Degree Classifications versus UK Degree Classifications
Converting overseas degree classifications on CVs to the local equivalent is vital, particularly in the UK.

British Class American GPA Secured Marks Level(%)
This table apparently comes from a US government department charged with assessing the levels so should be fairly accurate – see The Fulbright Commission pages for more info.
NB: We have also had a table sent to us by Mr Saif Basheer of the Kuwaiti Embassy in London.
I have been doing a comparative study for the UK and US degrees, and after extensive correspondence with UK universities and some in the US as I have arrived at this table (below);
