In the United States, blood glucose (BG) is measured in milligrams per deciliter (mg/dL). In most other countries, BG is measured in millimoles per liter (mmol/L). 1 mmol/L = 18 mg/dL Because of these differences, it is very important to make note of the units of measurement in order that we interpret diabetes data correctly, especially when talking with someone from another country. Although FelineDiabetes.com attempts to always use mg/dL, please look at the units of measurement each time. Since the FDMB is based in the US, when posting BG numbers, you'll probably receive more replies to your questions if metric numbers are converted to those understood in the US. Simply multiply the metric number by 18 to find the equivalent used in the US or use our handy-dandy little Blood Glucose Converter Calculator.
