Synonym discussion
Sense: noun/1
These four words all refer to tools for measuring or evaluating something, but they differ in scope and use. A metric is a specific numerical measurement used to track performance — it is quantitative and often part of a broader set (sales metrics, performance metrics). A benchmark is a reference point used for comparison, usually an established best practice or a past performance level that future results are measured against. An indicator is any sign or signal that shows the state or direction of something, which may or may not be numerical. A standard is a fixed, agreed-upon level of quality or achievement that something is judged against. For example: 'The company tracks customer satisfaction as a key metric (quantitative measure); their benchmark (comparison target) is the industry average; an early indicator (warning sign) of trouble was the drop in repeat visits; the industry standard (expected level) requires a 90% satisfaction rate.'

Etymology
The word 'metric' comes from the Greek word 'metron', meaning 'a measure'. This passed into Latin as 'metricus', then into French as 'métrique', and finally into English in the 19th century as both an adjective (relating to measurement) and a noun (a standard of measurement). The poetry sense arrived earlier, from Latin 'metricus' through French, referring to the measured rhythm of verse. The mathematical sense (metric space) was coined by the German mathematician Felix Hausdorff in the early 20th century, based on the idea of measuring distance.
