Someone asked how to convert from the American system of mg/dl to the UK system of mmol/l. I found this table on another site and the lower number on the left and slightly above is the system we use. I hope it is of use
Converting Blood Glucose Levels from mmol/l to mg/dl
There are two measurement sytsems for measuring blood glucose levels, the 'World Standard' of mmol/l and the US system of mg/dl
The US system will eventually be replaced by the World Standard, but until it does we need to be able to understand both.
The simple way to convert is to multiply or divide by 18, the following table makes it a little easier.
mmol/l
mg/dl
Fingertip Blood Sample Level
2
36
dangerously low
3
54
low, you need to eat something quickly
4
72
slightly low
5
90
normal before eating
6
108
normal before eating
7
126
normal before eating
8
144
maximum before bedtime
9
162
10
180
maximum 1-2 hours after a meal
11
198
