David has converted his numbers to mg/dl as used in the USA (and not many other places). But I believe he also uses mmol/l as you seem to do

There is a converter available on this forum page. I see it over on the Right under, Site Navigation.
So David's average of :
94.7 mg/dl becomes 5.26 mmol/l
96.4 mg/dl becomes 5.36 mmol/l
...and so on.
