Namely, mass = volume * density.

So how many grams of 500 ml is related to the density of the liquid. If it is filled with water, 500ml is 500g; if it is gasoline, 500ml is about 400g.

500ml is equal to 0.5 liter, and the unit conversion is as follows:

1L = 1000ml 1000ml = 1000 m3 = 1000 m3。 1 ml = 1 ml. 1 ml liquid water = 1 ml liquid water. 1 ml liquid water weighs 1 g at 4 degrees Celsius. 1 ml = 1 cm3.
