Lowe's Law

Lowe's Law states that the number of significant figures in a calculated result should reflect the precision of the least precise measurement used. In other words, when performing calculations with measured values, the final answer shouldn't be more precise than the least precise measurement involved. This principle ensures accuracy and honesty in reporting results, preventing overestimation of a calculation's certainty. For example, if you multiply a measurement recorded as 12.3 (3 significant figures) by another as 4.56 (3 significant figures), the result should also be expressed with 3 significant figures to maintain proper precision.
