NCEA results to US GPA

Can someone help calculate my NCEA results into the US GPA in a scale out of four, please!

I used this site as my guide for calculating. Math is below, but the result I get is 3.43 . I recommend you check yourself using the guide to ensure it’s correct!


(4x(85+46))

+ (3x(36+22))

+ (2x(34))

/

(155 + 68)

=

(524 + 174 + 68)

/

(223)

=

766/223

= 3.43
