1 cm3 = 1 ml 1 kg = 500g.

Density of water: 1 g/cm3 = 1 g/ml mass = density × volume.

Therefore, the mass of 500ml water is: 1 g/ml× 500ml = 500g.

Therefore, 500ml of water is equal to 1 kg.

1.ML: volume unit.

ML, when the unit of measurement is expressed in letters, the letters of unit symbols are generally lowercase; When the unit comes from a name, the first letter of the symbol must be capitalized. Only unit of volume's "l" is special, and this symbol can be written as capital L or lowercase L. This is because the symbol of "L" was originally lowercase, and it is difficult to distinguish lowercase L from Arabic numeral 1. Later, the International Metrology Conference made a resolution that the symbol of "L" can be written in uppercase L, so that lowercase L can be used together with uppercase L. This is the only symbol in the international system of units that can be capitalized instead of being named after scientists. According to the writing requirements of international units, the letter "m" is used to represent milli (10-3), and it should not be mixed with the letter "m" which represents mega (10 6).

2. Conversion method

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 liter? [ 1]? = 1 cubic decimeter = 1000 cubic centimeter = 1000 ml
