MEASURING WEIGHT
Weight tells us how heavy something is.
We measure weight using standard units! ⚖️
WHAT IS WEIGHT?
- Weight tells us how heavy something is.
- We measure weight using standard units like grams and kilograms.
- Weight can change if the pull of gravity changes.
Heavier means more weight. Lighter means less weight!
UNITS OF WEIGHT
Gram
(g)
Used to measure light things (e.g., paperclip, apple)
Kilogram
(kg)
Used to measure heavy things (e.g., rice pack, watermelon)
QUICK FACTS
- We measure weight using kilogram (kg) and gram (g).
- 1 kilogram (kg) = 1000 grams (g)
- Larger objects are measured in kilograms.
- Smaller objects are measured in grams.
- Use the right tool for accurate measurement.
- Balance scale helps us compare weights easily.
Always compare elements using matching standard scales!
MEASURING TOOLS
Different tools are used to measure weight:
⚖️
Balance Scale
Used to compare the weight of two things (heavier/lighter/equal).
📟
Weighing Scale
Used to find the exact weight of something instantly.
HEAVIER, LIGHTER OR EQUAL?
We use a balance scale to compare weights:

Weight of Rice =
kg
CONVERSION EXAMPLES
1. Convert kg to g:
2 kg = 2 × 1000 =
g
2. Half Kilogram value:
½ kg = 1000 ÷ 2 =
g
3. Quarter Kilogram value:
¼ kg = 1000 ÷ 4 =
g
4. Complex Multiplier Check:
3 kg = 3 × 1000 =
g
