Does the type of substance affect the conversion?
No, because ounces and grams measure mass, not volume or density. So, 4 oz of any substance converts to the same mass in grams, though volume it occupies can differ widely.
Are there different types of ounces?
Yes, the most common is the avoirdupois ounce used in the US and UK for general measurements. There is also the troy ounce used for precious metals, which equals 31.1035 grams, not 28.3495, so conversions differ by context.
