| 1. What are the basic units of measurement used in everyday life? |  |
Ans. The basic units of measurement used in everyday life include length (meter), mass (kilogram), time (second), temperature (Celsius or Fahrenheit), and volume (liter). These units help us quantify and compare different physical quantities in our daily activities.
| 2. Why is it important to understand units of measurement? | |
Ans. Understanding units of measurement is important because it allows us to accurately describe and compare quantities. It helps in performing calculations, understanding scientific concepts, and making informed decisions in areas such as cooking, shopping, and construction.
| 3. How do you convert between different units of measurement? | |
Ans. To convert between different units of measurement, you can use conversion factors. For example, to convert meters to centimeters, you multiply by 100 (since 1 meter = 100 centimeters). It’s essential to know the relationships between units and apply the appropriate factor for accurate conversions.
