Incompatible units

Those units are incompatible. There is no conversion factor. The milliliter is a unit of volume, whereas the gram is a unit of mass (or weight).

If you wish to know the weight in grams of a milliliter of a substance, then you must know the density of the substance.


1g = 1mL

For most things.

For heavier things, I.E. heavy metal alloys, density needs to be taken into consideration. However, for a basic Chemistry problem, or Cooking conversion (butter, bullion) 1g = 1mL.

The correct and complete answer is as follows:

Mass = Density x Volume
Milliliter is a volume and Gram is a mass. There is no set number since it varies depending on the matter you wish to convert. If you are converting water, they are equal.
