I19 – 3 [Issue 1] International System of Units (SI) Act FIRST SCHEDULE—continued Quantity Base unit Symbol Definition electric current ............... ampere ................ A ......... The ampere is that constant current which, if maintained in 2 straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum would produce between these conductors a force equal to 2 x 10-7 newton per metre length of conductor. thermodynamic temperature ...... kelvin ........ K ......... The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. luminous intensity .......... candela .............. cd ........ The candela is the luminous intensity in a given direction of a source which emits monochromatic radiation of frequency 540 x 1012hertz and of which the radiant intensity in that direction is 1/683 watt per steradian. amount of substance ........ mole ............... mol ........ The mole is the amount of substance of a system which contains as many elementary entities as there are atoms on 0.012 kilogram of carbon-12. When the mole is used, the elementary entities must be specified and may be atoms, molecules, ions, electrons, other particles or specified groups of such particles.

The radian is the plane angle between two radii of a circle which cut off on the circumference an arc equal in length to the radius. solid angle .................... steradian .............. sr ......... The steradian is the solid angle which, having its vertex in the centre of a sphere, cuts off an area of the surface of the sphere equal to that of a square with sides of length equal to the radius of the sphere.
