Metric Units Mass Kg Gm Practice Activities
Printable Class 4 maths worksheets for practising kilograms, grams, conversions, comparisons, and everyday mass word problems.
Practice that builds confidence
Understanding kg and g
These Class 4 measurement worksheets help children understand mass using metric units: kilograms and grams. Learners practise reading, comparing, converting, and using kg and g in familiar situations such as food packets, school bags, fruits, and household items.
The printable activities include direct conversion practice, mixed-unit questions, ordering by mass, and word problems that require careful unit thinking. Children build confidence with the key relationship 1 kg = 1000 g while learning when each unit is sensible to use.
Kilograms and grams describe how heavy an object is. In Class 4 maths, children move from simply naming the unit to using the relationship between them: 1 kg = 1000 g. These worksheets strengthen that idea through examples such as a 2 kg rice bag, a 500 g packet, or a pencil measured in grams.
Skill progression in the practice
The activities begin with choosing the correct unit for an object, then move to conversions such as kilograms to grams and grams to kilograms. Later questions ask children to compare, order, add, or subtract masses written in kg and g. Word problems encourage them to decide whether to convert first or work carefully with mixed units.
A simple home routine
Parents can make the practice concrete by using grocery items. Ask your child to read labels on flour, dal, biscuits, or fruit packets, then compare which is heavier. After one worksheet section, let them explain one answer aloud: “I changed 3 kg to 3000 g, so I could compare it with 2500 g.” This short explanation reveals whether the unit relationship is clear.
Classroom uses for teachers
Teachers can use these printables for measurement revision, maths centres, morning practice, or small-group support. They also work well after a weighing activity with a balance or kitchen scale. Children can solve independently first, then discuss which questions needed conversion and which could be solved by comparing the units directly.
Common errors to watch for
Many children confuse the direction of conversion, writing 1 kg as 100 g instead of 1000 g. Others compare only the number and ignore the unit, assuming 900 g is greater than 2 kg because 900 is larger than 2. In mixed-unit sums, remind learners to keep kg with kg and g with g, and to regroup when grams reach 1000.

Why iBloom worksheets help
iBloom worksheets use clear layouts, familiar Indian contexts, and varied question types so children do more than memorise a rule. A useful child-friendly strategy is: “Check the unit, convert if needed, then compare or calculate.” This habit helps children slow down and make sensible measurement decisions.
Helpful answers
Frequently asked questions
What do children practise in these Class 4 kg and g worksheets?
They practise identifying suitable units, converting between kilograms and grams, comparing and ordering masses, and solving simple measurement word problems.
What is the key conversion children need to know?
Children should know that 1 kilogram equals 1000 grams. This helps them convert kg to g and compare masses written in different units.
How can I help my child understand grams and kilograms at home?
Use real grocery packets and labels. Ask your child to find items marked in g and kg, compare their masses, and explain which item is heavier and why.
What mistakes are common in this topic?
Children often compare only the numbers and forget the units, or they convert 1 kg as 100 g instead of 1000 g. Mixed-unit addition and subtraction may also need careful regrouping.
Are these worksheets suitable for revision before a measurement test?
Yes. They cover the main Class 4 skills for metric mass, including unit choice, kg-g conversion, comparison, and word problems, making them useful for revision.
