Units & System of Units

Unit is defined as the numerical standard used to measure the qualitative dimension of a physical quantity. Mass or Force, Length and time are accepted as basic quantities, then all other quantities are derived quantities.

ü SYSTEM OF UNITS

         FPS : foot, pound, second
         CGS : centimeter, gram, second
         MKS : meter, kilogram, second
         SI     : System International

ü SI UNITS

Accepted throughout the world and is a modern version of the metric system. Length - metres (m), Mass - kilograms (kg), Time - seconds (s) are selected as the base units and Force in newtons (N) is derived from Newton’s Second law.

Electric Current – Ampere (A)
Temperature - Kelvin (K)
Amount of substance – mole (mol)
Luminous intensity – Candela (cd)

SP 16 :1980 - Design Aids for Reinforced Concrete to IS:456

The structural practice handbook SP:16-1980 Design Aids for Reinforced Concrete to IS:456-1978 has tables and charts that helps structural engineers to rapidly design simple sections. Even though the design aid is based on the 1978 code, it continues to be used without revision as there have been no major changes to Section 5, on which the design aid is based.
