The known and standardised mass of an object that serves as a reference point for calibrating scales and balances. It's a critical component in ensuring the accuracy and precision of weight measurement devices in various industries, from laboratory settings to manufacturing processes.
The precise and accurate measurement of the separation between two points. Calibrating distance measurement equipment, such as laser rangefinders or surveying instruments, ensures the reliability and accuracy of measurements for applications ranging from construction to scientific research.
