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.
