Class 5 Maths - TAMILNADU
Weight and Capacity
The Chapter 'Weight and Capacity' in Class 5 Mathematics under the Tamil Nadu Samacheer Kalvi syllabus introduces students to standard units of measurement for heavy and light objects, as well as liquids. Students learn how to measure weight in kilograms and grams, and capacity in litres and millilitres. They practice converting larger units to smaller units and vice versa, and solving practical word problems involving addition and subtraction of weights and capacities. Mastering these concepts is essential for daily life calculations and forms a strong foundation for higher-level mathematics and board exam success in middle school.

Units of Weight
Weight is measured in grams (g) for lighter objects and kilograms (kg) for heavier objects, where 1 kilogram equals 1000 grams.
Units of Capacity
Capacity is the amount of liquid a container can hold, measured in millilitres (ml) for small amounts and litres (l) for larger quantities.
Conversion of Weight
To convert kilograms to grams, multiply by 1000, and to convert grams to kilograms, divide by 1000.
Conversion of Capacity
To convert litres to millilitres, multiply by 1000, and to convert millilitres to litres, divide by 1000.
Addition and Subtraction of Measures
When adding or subtracting weights and capacities, always arrange the values in their respective columns (kg and g, or l and ml) before calculating.

Board Exam Info
In the Tamil Nadu (Samacheer Kalvi) Class 5 Mathematics term examinations, this chapter typically carries around 8 to 10 marks. Common question types include unit conversion sums, simple addition and subtraction word problems involving kilograms, grams, litres, and millilitres, and objective-type fill-in-the-blanks.
Frequently Asked Questions
How do I convert kilograms into grams?
You multiply the given kilogram value by 1000 because 1 kg is equal to 1000 g.
Why do we divide by 1000 when converting millilitres to litres?
Since a smaller unit (millilitre) is being changed into a larger unit (litre), and 1000 ml makes 1 litre, we divide the millilitre value by 1000.
Can we add grams and kilograms directly without conversion?
No, you must convert them to the same unit (either both into grams or both into kilograms) before adding them together.
