Mole : The amount of a substance that contains as many elementary particles or entities as there are atoms present in 12g of carbon-12 or C-12 is known as one mole.Candela : The luminous intensity in the perpendicular direction of a surface of a black body of area 1/600000 m 2 at the temperature of solidifying platinum under a pressure of 101325 N m -2 is known as one candela.Ampere: The current which, when flowing in each of two parallel conductors of infinite length and negligible cross-section and placed one meter apart in vacuum, causes each conductor to experience a force of 2 1 0 -7 newtons per meter of length is known as one ampere.
