What is 150g as liquid oz?

Answer 1

g = grams is a mass measure

fl oz = liquid ounces is a volume measurement

Only if the density (units of mass per unit volume) of the liquid is known can the question be answered unequivocally; then the conversion is rather straightforward.

Examples1)Let us first take water (because it is the easiest as the density is exactly 1)

150 grams of water divided by the density of 1 = 150 cubic centimeters or milliliters

150 ml ≈ 5.1 (5.07210338) fl oz

2)If we have Mercury with a density of 13.54 then:

150 / 13.45 ≈ 11.08 ml

11.08 ml ≈ 0.37 (0.374659372 ) fl oz
