Measure in Inches: 1 Inch = 2.24 centimeter - 1 English pound = 453 gram.
- Measure the fish from tip of the nose to the fork of the tail (this will be called the LENGTH MEASUREMENT ).
- Now measure around the fish in front of the Pectoral Fins (this will be called the GIRTH MEASUREMENT ).
- Now take the girth measurement and square it (multiply it by itself - if the measurement was 25 inches then would be: 25 x 25= 625 ).
- Now multiply the girth number squared (625) by the length measurement (lets say 125 inches) ( 625 x 125 = 78125 ).
- Now divide by 800 ( 78125 : 800 = 97.66 ) so your fishes weight is approximately 97.66 lbs.
Use the folowing divisors when making the final division in the above formula:
North Atlantic Sailfish - 1500
North Atlantic Spearfish - 1500
White Marlin - 1300
Striped Marlin - 950
North Atlantic Blue Marlin - 800
Black Marlin - 700
Indo / Pacific Blue Marlin - 650
For most other species normal used 840
