For example, a measurement made several times in which the same, or nearly the same value is obtained, indicates precise measurement. This does not necessarily mean that such measurements specify or approximate a real value, thus a precise measurement may not be accurate. still, even in technical usage the term is often used synonymously with accuracy.
  • The number of significant digits provided in a measurement or other value. The more significant digits, the more precise.
