Just to be even pickier, it's not the number of decimals, it's the number
of significant digits. So 32 oz. = .91 Kg (2 significant digits) or 910g
or 910,000mg or .00091t
But precision in packaged goods is sometimes better than indicated.
1 lb of butter does not equal .5 Kg, but probably 454g +/- 4g
This is because it is not a measurement, but a standard.
