There is a functional relationship between volume and mass: m=ρV, where ρ is the density. If the density is known, the mass can be calculated from the volume.
1 ml water is about 1 g, 1 ml alcohol is about 0.9 g, and 1 ml oil is about 0.8 g.
Gram, the unit of mass, symbol g. One gram is the mass of18×14074481c-12 atoms. The weight of one gram is approximately equivalent to the weight of one cubic centimeter of water at room temperature.
Extended data conversion:
1L (liter) = 1dm3 (cubic decimeter) = 0.00 1m3 (cubic meter)
1mL (ml) = 1cm3 (cubic centimeter) = 0.00 1dm3 (cubic decimeter)
1m3? > 1 dm3? = 1 L > 1 cm3? = 1mL, and the rate of advance between each stage is 1000.
1 l = 1 cubic decimeter = 1000 cubic centimeter = 1000 ml.
1 kg (1 kg) =11,000 g (1 kg)
1 kg = 500g (1 g = 0.002 kg)
1 mg = 0.00 1 g (1 g = 1000 mg)
1 μ g = 0.000 00 1 g (1 g = 1000000 μ g)
1 nanogram = 0.0000000 1 gram (1gram = 1000000000 nanogram)
