Units are standard measurements used to quantify various attributes like length, weight, and volume. For example, in the metric system, we use meters for distance, kilograms for weight, and liters for liquid volume. These units help us communicate and compare measurements easily, ensuring everyone understands the same values. In everyday life, we encounter units frequently. When cooking, recipes might call for cups or teaspoons to measure ingredients. In sports, we often hear about distances in meters or yards. By using consistent units, we can share information clearly and avoid confusion in our daily activities.
