HbA1c NGSP (%) ↔ IFCC (mmol/mol) Converter
Convert HbA1c between the US/India percentage and the European mmol/mol — the same result, two scales.
Two scales for the identical measurement: the old DCCT/NGSP percentage (US, India) and the SI IFCC mmol/mol (UK, Europe). Anchors: 6.5% = 48 mmol/mol (diagnosis), 7% = 53 (common target), 8% = 64. The IFCC scale was introduced to end inter-lab variability; the numbers look alien at first but map cleanly through this formula.
