Conversion chart from old to new HbA1c values

https://freestylediabetes.co.uk/what-is-diabetes/what-makes-glucose-levels-rise-and-fall/HbA1c

This shows a nicely formatted table; the basic values are reproduced below.

HbA1c values have changed and are now reported as a measurement in mmols/mol instead of the percentage previously given.

To make sense of the new units and compare these with old units and vice versa, use the HbA1c units converter table below.


Old unit = NGSP unit = %HbA1c
New unit = IFCC unit = mmol/mol
