How to Convert Kilograms and Grams in Maths (With Practice Questions)
FAQs on Metric Units of Mass – Kilograms and Grams Worksheet for Class 3
1. What is the difference between kg and g for Class 3?
The main difference is that a kilogram (kg) is used to measure heavier objects, while a gram (g) is used for lighter ones. For Class 3 students, the most important concept to remember is that 1 kilogram is equal to 1000 grams.
- Kilogram (kg): Used for items like a bag of rice, a watermelon, or a school bag.
- Gram (g): Used for items like a pencil, an apple, or a small packet of biscuits.
2. How do you convert kg to g in math?
To convert kilograms (kg) to grams (g), you simply multiply the number of kilograms by 1000. This is a fundamental skill taught in the Class 3 Maths syllabus on metric units.
- Step 1: Identify the number of kilograms you need to convert.
- Step 2: Multiply that number by 1000.
- Example: To convert 5 kg to grams, you calculate 5 x 1000 = 5000 g.
3. How do you solve mass word problems for Class 3?
To solve mass word problems, students should follow a few simple steps to understand and calculate the answer correctly. This worksheet provides excellent practice for these types of questions.
- Read Carefully: Understand what the problem is asking. Is it asking for a total weight (addition) or a difference (subtraction)?
- Identify Units: Check if the weights are in kilograms (kg) or grams (g).
- Perform the Calculation: Add or subtract the numbers as required.
- Write the Answer: Always include the correct unit (kg or g) in your final answer.
4. What objects are measured in grams and kilograms?
Objects are measured in grams (g) if they are light and in kilograms (kg) if they are heavy. This worksheet helps students identify the correct unit for different items.
- Measured in Grams (g): A feather, a coin, a chocolate bar, a key.
- Measured in Kilograms (kg): A sack of potatoes, a person's weight, a bicycle, a television.
