1, the conversion formula of milliliter and gram is: mass = density * volume. These are two different units, and you need to know the density before you can convert them.

2. Mass (usually in grams and kilograms) = density * volume (usually in milliliters, liters and cubic meters).

3. According to the density of water, the density of water is 1g/cm3, so the volume of 1g is equal to 1g divided by 1g/cm3, and the result is 1cm3, while 1 cm3 =/kloc.
