Detailed explanation-1: -A rule of thumb is a principle with broad application that is not intended to be strictly accurate or reliable for every situation. It is an easily learned and easily applied procedure for approximately calculating some value.
Detailed explanation-2: -A rule of thumb is a heuristic guideline that provides simplified advice or some basic rule-set regarding a particular subject or course of action. It is a general principle that gives practical instructions for accomplishing or approaching a certain task.
Detailed explanation-3: -In English, rule of thumb refers to an approximate method for doing something, based on practical experience rather than theory. The exact origin of the phrase is uncertain.
Detailed explanation-4: -A “rule of thumb” means a general principle built by personal experience, not a scientific calculation. It is not a 100% accurate rule, but considered as a pretty good estimate (example: A good rule of thumb in Boston is to check the weather each hour, as it can change so quickly and often).
Detailed explanation-5: -Actually, the phrase “rule of thumb” simply comes from the usage of a thumb as a unit of measurement. The old English “ynche” was defined as the breadth of a man’s thumb at the base of the nail. Then as now, thumb sizes varied, but not much precison was required in the Middle Ages.
