Converted by substance, taking water as an example: 700 mg =0.7 ml, and the conversion relationship is as follows:

1g = 1ml， 1g = 1000mg， 1ml = 1000mg，0.00 1ml = 1mg，0.7ml = 700mg。

1, mg is the international unit of mass. The English abbreviation is "mg". Usually used to measure the composition of liquids and drugs.

2. "gram" is the unit of mass of matter, and "gram" is represented by "g"; "mL" is the unit of volume of an object, and "mL" means "mL" [and 1 mL = 1 cubic centimeter ("centimeter" means "centimeter")].

3. The relationship between them is that with the different density of objects, there is a corresponding change in quantity.

For example, if the density of 1: water is 1g/ml (i.e. 1g/cm3, the same below), then the water with the mass of 1cm (1ml) is 1g, or the mass is 1g.

[Volume:1000ml =1000ml =1l; Mass:1000g =1000g =1kg. ]

Oz is Ounce (Ounce in English, abbreviated as Oz), which refers to fluid ounce and is a unit of capacity measurement. Both English and American units have this unit, slightly different. The UK 1 oz is 28.4 1mL, the US 1 oz is 29.57mL, and 16 oz is equivalent to 1 pint (USA).

The earliest is to drink different wines and choose different glasses. The capacity of the cup is the most important. Historically, ounces have been used as the liquid unit of wine. The United States does not use metric measures. A pound is about 454 grams, which is equivalent to 16 ounce. A pound is about the weight of a pint (less than 0.5 liter) of water, so there is a saying that a pint is equal to a pound. This is the world. In American weights and measures, a pint is equal to 16 ounce. In the British system, a pint is about 20 ounces.
