That's my understanding too; essentially the meters are identical, but with their units switched to reflect a particular country's usage, so their little computer chips will calculate the results in the relevant form - and this should in no way alter the actual method of acquiring the blood for testing.The strips I bought on a French island, in the Tropics worked perfectly well in my UK meter. In my personal expeience it is the meterr that decides how to express the number, as opposed to the strips.
I just walked into the La Pharmacie and asked for the strrips for my meter. I had my meter with me, just in case my French was unintelligible.
