CalculatorQueen A1C Calculator

A free, transparent A1C and estimated average glucose converter. Enter an NGSP A1C percentage to estimate eAG in mg/dL and mmol/L, or start with eAG and translate the same ADAG regression in reverse. The page keeps units and equations visible, includes a quick comparison table, and clearly explains that the result is a population-based translation rather than a diagnosis or substitute for laboratory testing, glucose monitoring, or professional care.

What problem it solves

Laboratory A1C uses percent while glucose reports may use mg/dL or mmol/L. The calculator translates those units without treating a single glucose reading as an A1C result.
