Blood glucose formula

[Guest]

The formula to discover an average blood glucose is: 28.7 X A1C – 46.7 = eAG

28.7 = lab constant
A1C = value returned by the A1C test (in the form of N.n, eg 5.6)
46.7 = lab constant
eAG = Average blood glucose

I'd like to reverse this formula, so I can enter an eAG and derive an estimated A1C

Entering eAG = 112
An A1C of 5.5 should be returned.

Got it: A1c = (46.7 + eAG) / 28.7
