Use grams to milliliters only when you know the substance’s density
Formula: mL = g ÷ density (g/mL)
For water, 1 g = 1 mL
For other liquids, check the density first
Example: 10 g of water = 10 mL
Example: 10 g of oil is not 10 mL unless its density is 1 g/mL
If you share the substance, I can convert it for you
