NCERT Solutions for Class 5th Maths Chapter 8 Weight and Capacity

About this chapter
Weight tells how heavy a thing is. A milligram (mg) is the smallest unit here — an ant weighs only 1 mg to 5 mg. A gram (g) is bigger: a sugar sachet is 5 g. A kilogram (kg) is bigger still: a rice bag is 5 kg. A quintal is 100 kg and a tonne is 1,000 kg — those are for trucks, elephants and grain stores. Always ask, is this thing light or heavy? , and then pick the unit. The magic number is 1,000. 1,000 mg = 1 g. 1,000 g = 1 kg. 1,000 kg = 1 tonne. Going from a big unit to a small unit, multiply by 1,000 . Going from a small unit to a big unit, divide by 1,000 . So 3 kg = 3 × 1,000 = 3,000 g, and 5,000 g = 5,000 ÷ 1,000 = 5 kg. Mixed amounts split into two pieces. 3 kg 500 g means 3 kg and 500 g. Change only the kg part and then add the grams: 3 kg = 3,000 g, so 3 kg 500 g = 3,000 + 500 =

Quick revision
| Word | What it means | Where it appears | Example |
|---|---|---|---|
| Weight | How heavy a thing is | Chapter title, page 104 | A rice bag weighs 5 kg |
| Milligram (mg) | The smallest weight unit in this chapter; 1,000 mg = 1 g | Milligram, page 108 | An ant weighs 1 mg to 5 mg |
| Gram (g) | 1,000 g make 1 kg | Check! Check!, page 104 | A water bottle weighs 650 g |
| Kilogram (kg) | The everyday unit for shopping weights | Page 104 onwards | A bed weighs 60 kg |
| Quintal | 100 kg | Did you know?, page 109 | 5,000 kg = 50 quintals |
| Tonne | 1,000 kg, or 10 quintals | Did you know?, page 109 | A whale weighs 200 tonnes |
| Weighing balance / scale | The machine that shows a weight; the needle points at the reading | Let Us Do, page 104 | The needle at 600 g |
| Double number line | Two lines one above the other — the same amount in two units | Pages 105, 106, 108, 114 | 1 kg above 1,000 g |
| Capacity | How much a container can hold | Measuring Capacity, page 113 | A bucket holds about 20 l |
| Millilitre (ml) | The small capacity unit; 1,000 ml = 1 l | Page 113 | A glass holds 250 ml |
| Litre (l) | The everyday capacity unit | Page 113 onwards | A water bottle holds 1 l |
| <, >, = | Less than, more than, equal to | Pages 107, 109, 116 | 1,600 g < 1,700 g |
