The main unit of volume unit is liter (L), 1L = 1000ml, 1ml = 1m3 centimeter, 1000ml = 1m3 decimeter = 1L. 150ml is a traditional unit of mass in East Asia. The traditional one kilogram is equal to 16 Liang, so there is the idiom "half a kilogram". The one liang used in jewelry stores in Hong Kong and Macao is equal to 31.25 grams, which is different from the one liang used in China is equal to 50 grams.
The density of 150 ml depends on the density. For example, 150 ml of water is just three Liang, and less than three Liang if it is oil, but more than three Liang if it is honey.
Ml is a unit of measurement. When the unit of measurement is expressed in letters, the unit symbol letter is generally lowercase. When the unit comes from a person's name, the first letter of the symbol must be capitalized. （150HaoShengShiJiLiang）
