Weight Worksheets | Free - Distance Learning, worksheets and more ... - Free Printable

Let's solve each question in the worksheet "Estimating Weight (Metric)" by choosing the best estimate for the weight of each object using grams (g) or kilograms (kg). We’ll go through each one step by step and explain our reasoning.

Key Concepts:

- 1 gram (g) ≈ weight of a paperclip
- 1 kilogram (kg) ≈ weight of a thick book
- 1 kg = 1,000 grams
- 1 kg ≈ 2 pounds

1) Adult Horse

- A horse is very heavy.
- An average adult horse weighs around 500 to 1,000 kg.
- The options:
- A. 400 grams → too light (less than a pound)
- B. 400 kilograms → plausible
- C. 30 grams → tiny
- D. 30 kilograms → about 66 lbs, like a small dog

✔ Answer: B. 400 kilograms

2) Gallon of Milk

- A gallon of milk is about 8 pounds, which is roughly 3.6 kg.
- Let’s convert: 3.6 kg = 3,600 grams
- Options:
- A. 1 gram → no
- B. 500 grams → ~1.1 lbs → too light
- C. 4 kilograms → 4 kg = 4,000 grams → close to 8 lbs
- D. 30 kilograms → 66 lbs → way too heavy

✔ Answer: C. 4 kilograms

3) Ruler

- A typical ruler is made of plastic or wood and is very light.
- It might weigh around 20–30 grams.
- Options:
- A. 1 gram → too light
- B. 999 grams → almost 1 kg → too heavy
- C. 20 grams → reasonable
- D. 30 kilograms → extremely heavy (like a person)

✔ Answer: C. 20 grams

4) Lawn Mower

- A standard push lawn mower weighs between 50–100 pounds, which is about 22–45 kg.
- Options:
- A. 500 grams → 0.5 kg → less than a pound → too light
- B. 100 kilograms → 220 lbs → possible for a heavy mower
- C. 200 grams → 0.2 kg → too light
- D. 22 kilograms → ~48.5 lbs → plausible

But let’s think: most push mowers are around 50–70 lbs, so 22 kg (~48.5 lbs) is reasonable.

✔ Answer: D. 22 kilograms

5) Frog

- A common frog (e.g., green frog) weighs about 30–50 grams.
- Options:
- A. 5,000 kilograms → 5 tons → absurd
- B. 5,000 grams → 5 kg → 11 lbs → too heavy
- C. 30 grams → yes!
- D. 30 kilograms → 66 lbs → impossible

✔ Answer: C. 30 grams

6) Baseball Cap

- A baseball cap is light — maybe 80–100 grams.
- Options:
- A. 85 grams → perfect
- B. 5 kilograms → 11 lbs → too heavy
- C. 5 grams → too light
- D. 200 grams → 7 oz → a bit heavy, but possible?

But 85 grams is more realistic.

✔ Answer: A. 85 grams

7) Dresser

- A wooden dresser can weigh 100–200 pounds.
- That’s 45–90 kg.
- Options:
- A. 350 grams → 0.35 kg → like a bag of sugar → too light
- B. 70 kilograms → 154 lbs → possible
- C. 20 grams → too light
- D. 500 kilograms → 1,100 lbs → too heavy (like a small car)

✔ Answer: B. 70 kilograms

---

8) Envelope

- A standard envelope is very light — a few grams.
- A letter with paper inside is about 10–20 grams.
- Options:
- A. 30 grams → a bit heavy but possible
- B. 1 gram → too light
- C. 200 kilograms → absurd
- D. 675 grams → over half a kilo → too heavy

But 30 grams is reasonable for a filled envelope.

✔ Answer: A. 30 grams

---

9) Clothes Iron

- A clothes iron weighs about 1–2 kilograms.
- Common irons are around 1.5 kg.
- Options:
- A. 100 grams → 0.1 kg → too light
- B. 15 kilograms → 33 lbs → way too heavy
- C. 2 kilograms → good
- D. 15 grams → too light

✔ Answer: C. 2 kilograms

---

✔ Final Answers:

| Question | Answer |
|--------|--------|
| 1 | B. 400 kilograms |
| 2 | C. 4 kilograms |
| 3 | C. 20 grams |
| 4 | D. 22 kilograms |
| 5 | C. 30 grams |
| 6 | A. 85 grams |
| 7 | B. 70 kilograms |
| 8 | A. 30 grams |
| 9 | C. 2 kilograms |

✔ Summary:

This worksheet helps students estimate real-world weights using metric units. The key is understanding the scale:
- Grams for small objects (paperclip, frog, ruler, envelope)
- Kilograms for heavier items (horse, dresser, iron, milk)

Always compare to familiar references (like a paperclip or book) to make good estimates.
