Fellow blogger and person with diabetes, Jenny, has developed a web widget that converts average blood glucose reading to A1Cc. Go check it out now.
I had some spare time this morning and turned my A1c/Avg converter into a widget you can put on your own blog or web pages. It will convert A1c to average blood sugar and vice versa using either mg/dl or mmol/L. You can also use it to convert mmol/L and mg/dl back and forth. Enter one measurement, and the converter will fill in the others.
