Class 5 Maths - ODISHA
Weight and Capacity
The chapter 'Weight and Capacity' in Class 5 Mathematics for Odisha BSE students introduces the fundamental concepts of measuring heavy and liquid objects. Students learn standard units like kilograms, grams, milligrams for weight, and litres, millilitres for capacity. The chapter focuses on practical life skills such as converting larger units to smaller units and vice versa, as well as performing addition, subtraction, multiplication, and division on weight and capacity measurements. Mastering this chapter is essential for scoring well in the Board of Secondary Education (BSE) Odisha examinations, as it frequently features in word problems and conversion-based numerical questions.

Units of Weight
Weight is measured in kilograms (kg), grams (g), and milligrams (mg). The standard unit for heavier objects is the kilogram, while lighter objects are measured in grams.
Units of Capacity
Capacity measures the volume of liquids. The standard units are litres (l) and millilitres (ml), where litres are used for larger quantities like milk or water, and millilitres for smaller amounts.
Conversion of Weight
To convert kilograms to grams, multiply by 1000 (since 1 kg = 1000 g). Conversely, to convert grams to kilograms, divide by 1000.
Conversion of Capacity
To convert litres to millilitres, multiply the value by 1000 (since 1 l = 1000 ml). To convert millilitres to litres, divide the value by 1000.
Arithmetic Operations on Measurement
Students learn how to add, subtract, multiply, and divide quantities of weight and capacity by arranging them in separate columns for larger and smaller units.

Board Exam Info
In the Odisha (BSE) Class 5 Mathematics examinations, this chapter typically carries around 6 to 8 marks. Common question types include direct unit conversions (e.g., convert 5 kg 250 g into grams), simple addition or subtraction of weights and capacities, and word problems based on daily life situations like buying rice, oil, or milk.
Frequently Asked Questions
How do I convert kilograms into grams?
To convert kilograms into grams, you simply multiply the given number of kilograms by 1000.
Why do we divide by 1000 when converting millilitres to litres?
Since 1 litre is equal to 1000 millilitres, changing a smaller unit (ml) to a larger unit (l) requires division by 1000.
How should I arrange numbers with both kg and g for addition?
Write kilograms (kg) under the kg column and grams (g) under the g column, ensuring there are always 3 digits in the grams column before adding.
