How do you convert grams to milliliters?
You need to know the density of the material you are weighing,
which is typically given in grams per milliliter. You then multiply
the weight in grams of the object by its density to get its volume
For water: 1g = 1mL For anything else you need to know it's density
to convert from mass to volume.
it depends of what you are mesuring, if it is water, the proportion
is 1:1, 15ml of water is 15grams etc.
