How do you find percent change?
February 20th, 2023
See explanation.
I assume you have 2 measurments start – ##x_s## and finish – ##x_f##.
To calculate the change you use this formula:
##c=|x_f-x_s|/x_sxx100%##
Example:
Let’s say that a temperature changed from ##300K## to ##330K##. To calculate the percent change I use the formula:
##c=|330-300|/300xx100%=30/300xx100%=1/10xx100%=10%##
From these calculations we see that the temperature change (increase) is ##10%##
