Chances are you may have seen a blood sugar reading that says 70 mg/dL and have no idea what that means.

You might be in the same boat if you’ve seen one that says 3.8 mmol/L and it makes no sense to you.

That’s because the United States and the rest of the world measure things differently from each other. If you’re used to metric measurements, this calculator will help you understand blood glucose values that are not measured in metric.

A quick tip is to divide the non metric number by 18 and you’ll have the value your looking for. But in case you want the number faster, you can use my calculator below.
