Such standard is called a unit of a quantity. Measurement implies a comparison with a standard value. To say that a rope is 30 m long is to say that is 30 times as long as an object whose length has been defined to be 1 meter. Fundamental Units Basic units of mass (M), Length (L), time (T) are known as fundamental units. These are also known as the primary fundamental unit.

  Instrument: An instrument may be defined as a device for determining the magnitude of a quantity for a physical variable. Measurement and Measurement System: Instrumentation is the operation for determining the value of the quantity. A measurement or instrumentation system is a means used to carry out the measurement. It generally involves using an instrument as physical means of determining a quantity or variable. The purpose of the measurement system is to give the user numerical value corresponding to the variable be measured. For a variety of reasons, the numerical value may not actually be the true value of the variable. Due to various errors, the measured values will not be exactly equal to the true value of the quantity under measurement. Signal measurement
