Unit of Mass and Standards of Mass, rise to two fundamental laws, namely (1) conservation of mass and (2) conservation of energy. But in higher classes, we were told that Albert Einstein combined the two concepts into one, which became the principle of equivalence of mass and energy.

Testing of Electronic Balances, digit on the extreme right of the display. It is therefore expected that errors permitted should be an integral multiple of the mass value of unit digit of the extreme right of the display. However it is not true. We can certainly check the balance or weighing machine in terms of a fraction of the last digit .

Group Weighing Method,hod is called as one to one comparison method. The second one is to take a group of weights and compare it against a standard of suitable nominal value. The weights from the group are further subdivided into sub-groups of equal denominations and inter-comparison, in all possible ways, is carried out. This method is known as group weighing method.
