How the conversion works

Multiply by 0.03527396195 to go from grams to ounces, or by 28.34952313 to go back the other way. Both figures are exact rather than rounded: they follow from the definitions of the units, not from anybody measuring something.

The exactness is more interesting than it sounds. Since the International Yard and Pound Agreement of 1959, the inch has been defined as exactly 25.4 millimetres and the pound as exactly 0.45359237 kilograms. Every other imperial length and weight follows from those two by whole-number ratios, which means the imperial system is now defined in terms of the metric one rather than alongside it.
