What method does it use?
mmol/L = mg/dL × 0.02586. For total cholesterol units only. Not a triglyceride converter, diagnosis or treatment recommendation.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
