The half-width of a function with a maximum is the difference between the two argument values for which the function values have fallen to half of the maximum, i.e. the “width at half height”.
Definition: A function f(x) has a maximum at 
. At the points 
and 
, the value of the function has fallen to half of the maximum:
Then the half-width is the difference 
.
Conversion
For a fixed function form, the half-width can be converted into differently defined widths of the function. For example, the FWHM and the standard deviation can be converted into each other for the normal distribution:
