Can I convert mg to oz by multiplying instead?
No, multiplying mg by any number won’t give the correct oz value, because ounces are bigger units. You must divide by 28,349.5 to reduce the milligram amount into ounces accurately.
Is the conversion result exact or approximate?
The conversion uses the exact factor 28,349.5 mg per oz, so mathematically it’s exact. However, practical measurements may vary due to rounding or precision limits in instruments.
Why do the results show many decimal places?
