Sorry if the Title is misleading.

I keep record of my blood sugar in excel 2003 that I send to my doctor weekly.

What I would like to do is, instead of typing the readings and mmol/L at the end in every cell,
is to just type in the reading (example 5.5) then tab of the cell and have excel populate the cell with mmol/L automatically after the reading.

Can it be done?

Thanks in advance
