Why 18?

It’s the standard conversion factor for glucose.

Can I round?

Yes, to 1 decimal for mmol/L or whole numbers for mg/dL.

Most differences come from rounding and display settings.

Do I need to store both versions?

One is enough if units are clearly specified in each record.

The converter is not a diagnostic tool.
