Gram and milliliter are two different units and cannot be directly converted. If you want to convert, you must know the density of the liquid. According to the density formula m=ρv, (ρ is pronounced rou, a sound), that is, mass equals density times volume. For example, it is known that the density ρ of water is per cubic centimeter 1g, that is, per milliliter 1g, then the mass of water with a volume v of 1ml is: m =1g/ml× 1ml =1g. So if we take low-gluten flour as an example, then 1 ml of low-gluten flour is equal to 1 g.
