1 litre of liquid is made up of a full 750 ml bottle and an additional third of a bottle. 1,000 millilitres, or ml, make up one litre.
A 750 ml bottle contains 0.75 litres, or three-quarters of a litre. The basic unit of volume measurement in the metric system is the litre, which is somewhat larger than a quart in American measurements.
A 750 ml bottle is equivalent to somewhat more than 25 fluid ounces, around 1 pint, and slightly more than 3 standard cups because one ounce of liquid is equal to about 30 millilitres. 200 ml roughly equals one normal cup.
