Metric unit conversion worksheet for students to practice comparing and calculating length, mass, and capacity.

Let's solve this step-by-step, starting with Section A, where we need to compare two quantities and fill in the correct symbol: `<`, `=`, or `>`.

---

🔹 Section A: Fill in the gap with the correct symbol

We'll convert both sides to the same unit before comparing.

#### 1) 6000 g vs 7 kg
*(Already given as example)*

Convert 7 kg to grams:
7 kg = 7 × 1000 = 7000 g

So:
6000 g < 7000 g → < ✔

---

#### 2) 500 mm vs 50 cm

Convert both to same unit. Let's use cm:

- 500 mm = 500 ÷ 10 = 50 cm
- 50 cm = 50 cm

So:
50 cm = 50 cm → =

✔ Answer: =

#### 3) 3000 ml vs 2.5 l

Convert both to liters (L):

- 3000 ml = 3000 ÷ 1000 = 3 L
- 2.5 L = 2.5 L

Compare:
3 L > 2.5 L → >

✔ Answer: >

---

#### 4) ½ kg vs 500 g

Convert both to grams:

- ½ kg = 0.5 × 1000 = 500 g
- 500 g = 500 g

So:
500 g = 500 g → =

✔ Answer: =

---

#### 5) 0.8 km vs 820 m

Convert both to meters:

- 0.8 km = 0.8 × 1000 = 800 m
- 820 m = 820 m

Compare:
800 m < 820 m → <

✔ Answer: <

---

#### 6) 4 l vs 410 ml

Convert both to milliliters:

- 4 L = 4 × 1000 = 4000 ml
- 410 ml = 410 ml

Compare:
4000 ml > 410 ml → >

✔ Answer: >

🔹 Section B: Fill in the gaps to make the sums correct

We now solve each equation.

---

#### 1) 200 cm + 500 cm = _____ cm

Add directly:
200 + 500 = 700 cm

✔ Answer: 700

---

#### 2) 4 kg + _____ g = 6 kg

Convert 6 kg – 4 kg = 2 kg
Now convert 2 kg to grams:
2 kg = 2 × 1000 = 2000 g

✔ Answer: 2000

---

#### 3) 100 ml + 900 ml = _____ l

Add: 100 + 900 = 1000 ml
Convert to liters: 1000 ml = 1 L

✔ Answer: 1

---

#### 4) 70 mm + _____ cm = 11 cm

First, convert 70 mm to cm:
70 mm = 70 ÷ 10 = 7 cm

Now:
7 cm + ? cm = 11 cm
→ ? = 11 – 7 = 4 cm

✔ Answer: 4

---

#### 5) _____ m + 1 km = 1.5 _____

We know:
1 km = 1000 m
So:
? m + 1000 m = 1.5 km → because 1.5 km = 1500 m

So:
? m = 1500 – 1000 = 500 m

Now fill in:
500 m + 1 km = 1.5 km

✔ Answers:
First blank: 500
Second blank: km

---

#### 6) 8000 ml – 3 l = _____ l

Convert 8000 ml to liters:
8000 ml = 8 L

Now:
8 L – 3 L = 5 L

✔ Answer: 5
