What scale is that glucose level measured in? I ask because my partner is diabetic but and those levels are supposed to be between 6 and 12 mmol / L. Clearly 100 is not expressed as mmol/L.
Conversion is mg/dl -> mmol/l divide by 18 approx.
See http://www.soc-bdr.org/rds/authors/unit_tables_conversions_a...
Note, this is only for glucose; there are different factors depending on what is measured, e.g. cholesterol is different.
