Measuring volume
Volume is a measurement that determines how much space an object takes. On the other hand, capacity measures how much liquid a vessel can carry when it is full. Let us understand this by example if you have a bottle of juice which is 500 ml, but the liquid in it is 300 ml. In this case, the bottle’s capacity if 500ml and the volume of water inside it is 300ml.

If you want to calculate 3 litres of water into fluid ounces, then multiply 3* 33.814, making 101.442.
Its formula is:
Fluid ounce = liter *33.8140226 
How many water bottles are there in a litre?
For finding out how many water bottles sized in oz can fit in litres, you require to multiply the number of litres by 33.8140226 and divide by the size of the water bottle in US fluid ounces. Therefore the formula is
No. of water bottles= litre*33.8140226/size of the water bottle in fluid ounces.
