The IEEE standard glossary of software engineering provides the following definitions of measures and metrics. A measure is a standard, unit, or result of measurement. A metric is a quantitative measure of the degree to which a system, entity, or process possesses a given attribute. Without a trend to follow or an expected value to compare against, a measure gives little or no information. It especially does not provide enough information to make meaningful decisions. A metric is a comparison of two or more measures. Therefore, a measure by itself doesn’t provide much understanding unless it is compared with another value of the measure i.e., it becomes a metric.
