SI UNITS
OBJECTIVE:

To describe the
International
System of units

The International System of Units is the
modern form of the metric system. It
comprises a coherent system of units of
measurement built around seven base units
K –Kelvin
S – Second
m – Meter
Kg – Kilogram
cd – Candela
mol – Mole
A - Ampere
