n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

n: the ability of a measuring instrument to indicate values closely approximating the true value of the quantity measured.

the closeness of agreement between the measure value and the exact value.

n: the degree of conformity to each other of measurements repeated under specified conditions, irrespective of whether they are close or far from the true value.

n: the interval within which the true value is expected to lie with a stated degree of confidence.

n: the quotient of the absolute error divided by the true value of the measured quantity. This multiplied by 100 gives the relative error as a percentage.

n: the theoretically correct amount. In practice, it is represented by the standard being used for comparison, such as a prover.
