Answer» SI system represents the “International system of units”. It was adopted in 1971 at the general conference on Weights and Measures : S.I. system has seven fundamental units. They are 1. meter for length, 2. kilogram for mass 3. second for time 4. ampere for electric current 5. Kelvin for temperature 6. candela for luminous intensity 7. mole for Amount of substance. There are 2 supplementary units, They are 1. radian for measurement of angle in a plane. 2. steradian for measurement of angle in solid angle.
