How many ml is 5 kg of flour?

It is not possible to convert kilograms (kg) to milliliters (ml) because these units of measurement are used for different purposes. Kilograms are a unit of mass, while milliliters are a unit of volume. To convert between these two units, you need to know the density of the substance you are measuring. The density of flour varies depending on the type of flour and how finely it is ground, so it is not possible to give a general conversion factor.
