- Enter the capacity of one bottle in millilitres.
- Read the bottle equivalents, full bottles, remaining volume and whole bottles to carry.
Worked example
A user-entered target of 2000 mL with a 750 mL bottle is 2.666667 bottle equivalents: 2 full bottles plus 500 mL. Carry 3 bottles to cover it.
Formula, accuracy & limitations
Bottle equivalents = target ÷ capacity. Whole bottles to carry = round up.
Enter a target you have chosen. The calculator does not prescribe fluid intake.
Calculations use your inputs. Main numeric values show up to six decimal places, percentages up to two, and chart labels up to four. Time results use hours, minutes and seconds. Very small nonzero values use scientific notation.
Plan capacity without changing your target
Choose your own volume target and use the usable capacity of the bottle. Bottle equivalents can be fractional; the carry count rounds upward. The illustration is capped for readability and does not show every bottle when the target is large.

Frequently asked questions
Which bottle count should I use when packing?
Whole bottles to carry rounds upward to cover your chosen target. Full bottles counts completely consumed bottles; the remainder tells you how much of the next bottle is needed.
Does a target of 2000 mL mean I should drink that much?
It is an editable example, not a personal intake recommendation. Enter a target appropriate to your own plan; this page only divides volume by bottle capacity.
