MEASUREMENT

Introduction

In the scientific method, observations are very important. How good a theory is depends on how good the observations are which support the theory. The most useful observations are those which involve measurements. In this unit you will learn about characteristics of measured quantities, significant figures, commonly used in units in chemistry and unit conversions.
