# Measurement

Measurement is an important branch of mathematics used in everyday life to quantity a measure, an amount, or a dimension. It has applications in finding out the length, mass, time and capacity of objects.

Since the start of civilisations, poeple have been using different ways of measurement for trading purposes (barter system), to record their grains in storage and ways to measure length, time, mass and capacity. We will take a brief look at the history of measurement, and the evolution of the standardised unit of measurement.

Given an object (polygon), we can find its perimeter by measuring along its boundary. The perimeter of a circle is called the circumference. The amount of space occupied by a 2D or a flat shape is called its area, while the amount of space inside the solid is called its volume. We will look at the measurement units, formulae and methods in depth in the various sub-topics on the right hand menu.

We will also look at conversion rules between different units of measurements, and use the Simpson's Rule to find the areas of irregular and curved shapes. We will also learn about the different instruments used to measure quantities and its applications in everyday life.
