The calculation process is as follows:

1, the specific gravity of normal milk is between1.028 ~1.033 at 20℃;

2. The mass of 250ml milk is about 257.5g, and the density of pure milk is (1.1~1.2) ×103kg/m3!

3, 250 ml of water is 250 grams, that is to say, 250 ml of milk is a little more than half a catty. Equal to 257~258.25 grams.

Extended data:

It is enough for ordinary people to drink 250ml of a box of pure milk a day. The protein, fat, calcium and so on contained in it can meet the needs of people's daily life. It is suggested that everyone drink a box of pure milk 250ml every day to bring enough nutrients to the body and meet the daily energy support of the body.

Milk is rich in nutrients such as protein, fat, vitamins and minerals, and milk protein contains amino acids necessary for human body. Milk fat is mostly short-chain and medium-chain fatty acids, which are easily absorbed by the human body; Potassium, phosphorus, calcium and other minerals have reasonable proportions and are easy to be absorbed by the human body.
