This screen gives details of the calculations performed to convert the length given in

The weight of a fish at a given length may be estimated using one or more length-weight relationship formulae obtained from fishbase.org for that species. These are expressed for a specific length type (e.g. fork length, total length) and sometimes it is necessary to convert a fish length from one type to another in order to use them. The
