Making the assumption that by 0.33 litres you mean 33 / 100ths of a litre, rather than one third:
Rounded to two decimal places, 1 cup = 236.59 millilitres.
0.33 litres = 330 millilitres.
Rounded to two decimal places, 330 / 236.59 millilitres = 1.39 cups.
8 cups of water is approximately two (1.892) liters.
That is 72 cups.
That is 17.637 cups.
There are approximately 15.9 cups of water in 3.78 liters.
12.68 cups 1 liter = 4.22 cups 1 cup = 0.23 liter
That is 11.8 cups
3.96 liters equals approximately 16 and 3/4 cups.
1.41 liter 1 liter = 4.22 cups 1 cup = 0.23 liter
0.3 liters = approximately 10.1 fluid ounces.
2.48 liters 1 liter = 4.22 cups 1 cup = 0.23 liter
3.31 liters 1 liter = 4.22 cups 1 cup = 0.23 liter
If you look at a regular bottle of water (591 ML i think) then you would have to drink about 8 bottles of water (as because cups can be any size).
