FAQs on Quick Revision: Measurement Video Lecture - Mathematics for Class 1

1. How do you measure length in the metric system?
Ans. Length in the metric system is measured using units such as millimeters, centimeters, meters, and kilometers. To measure length, use a ruler or a tape measure and align the object to be measured with the zero point on the ruler or tape measure. Read the measurement where the object ends.
2. What is the difference between mass and weight?
Ans. Mass is the amount of matter in an object and remains constant regardless of its location, while weight is the force of gravity acting on an object and can vary depending on the gravitational pull. Mass is commonly measured in grams or kilograms, while weight is measured in newtons or pounds.
3. How do you convert units of measurement?
Ans. To convert units of measurement, use conversion factors to multiply or divide by the appropriate conversion factor. For example, to convert meters to centimeters, multiply by 100 because there are 100 centimeters in a meter. Make sure to cancel out the original unit to ensure correct conversion.
4. What are some common tools used for measuring?
Ans. Some common tools used for measuring include rulers, tape measures, scales, thermometers, and measuring cups. These tools are designed to measure length, weight, temperature, and volume accurately.
5. Why is it important to use standard units of measurement?
Ans. Standard units of measurement provide consistency and accuracy in communication and calculations across different regions and disciplines. Using standard units ensures that measurements are universally understood and can be compared easily.
