Are weight ounces and fluid ounces the same?
No. An ounce (oz) measures mass, while a fluid ounce (fl oz) measures volume. Converting a liquid volume to grams requires the liquid's density, so this page does not convert fluid ounces.
Does this converter use troy ounces?

How many decimal places should I keep?
Four decimal places is usually enough for everyday comparison. Keep more digits only when the original measurement and your task support that precision; extra displayed digits do not make a scale more accurate.
