Most people report fish caught in inches.. I think because just about everyone carries a measuring tape with them. I've never seen any one whip out a heavy brass scale they been hauling with them and weigh a fish . To give an accurate weight you must keep the fish bring it in and get it weighed.. Or if you have fished for some time ,(years) kept and weighed a bunch of fish ,you have some refference to guess the weight . I really don't care how fish are reported pounds or inches, I get the picture . Some people take great offense.. I don't know why . You know a newbe is going to measure and give report in inches.. Must suc everyone yelling "pounds" at you .
