The document discusses units and measurement. It begins by providing examples of the longest bridges in Malaysia and worldwide, and the tallest building in Malaysia and worldwide. It then introduces the International System of Units (SI) and its seven base units: kilogram, meter, second, ampere, kelvin, mole, and candela. Several derived units are also described such as area, volume, velocity, and acceleration. Prefixes used with SI units are defined, ranging from deca to yocto. Methods for converting between units are demonstrated, such as kilometers to meters and feet. Examples of solving unit conversion problems are provided.

8. 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
