Water Change Formula
The following two example problems outline the steps and information needed to calculate the Water Change.
WC = WCV / WT * 100
Variables:
- WC is the Water Change (%)
- WCV is the volume of the water change (L)
- WT is the volume of the tank (L)
To calculate the water change percentage, divide the volume of the water change by the volume of the tank, then multiply by 100.
How to Calculate Water Change?
The following steps outline how to calculate the Water Change.
- First, determine the volume of the water change (L).
- Next, determine the volume of the tank (L).
- Next, gather the formula from above = WC = WCV / WT * 100.
- Finally, calculate the Water Change.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
volume of the water change (L) = 4
volume of the tank (L) = 10
WC = WCV / WT * 100 = ?
