This "Metric Mania" worksheet challenges students to master metric abbreviations, perform unit conversions, and compare measurements across length, mass, and volume.

Let's solve the "Metric Mania" worksheet step by step.

---

Part 1: Write the correct abbreviation for each metric unit.

1) Kilogram → kg
2) Meter → m
3) Gram → g
4) Milliliter → mL
5) Millimeter → mm
6) Liter → L
7) Kilometer → km
8) Centimeter → cm
9) Milligram → mg

---

Part 2: Try these conversions.

We use metric prefixes:
- kilo (k) = 1000
- centi (c) = 0.01
- milli (m) = 0.001
- 1 meter = 100 cm = 1000 mm
- 1 liter = 1000 mL
- 1 gram = 1000 mg
- 1 kg = 1000 g

---

#### Conversions:

10) 2000 mg = _______ g
→ 2000 ÷ 1000 = 2 g

11) 104 km = _______ m
→ 104 × 1000 = 104,000 m

12) 480 cm = _______ m
→ 480 ÷ 100 = 4.8 m

13) 5.6 kg = _______ g
→ 5.6 × 1000 = 5600 g

14) 8 mm = _______ cm
→ 8 ÷ 10 = 0.8 cm

15) 5 L = _______ mL
→ 5 × 1000 = 5000 mL

16) 198 g = _______ kg
→ 198 ÷ 1000 = 0.198 kg

17) 75 mL = _______ L
→ 75 ÷ 1000 = 0.075 L

18) 50 cm = _______ m
→ 50 ÷ 100 = 0.5 m

19) 5.6 m = _______ cm
→ 5.6 × 100 = 560 cm

20) 16 cm = _______ mm
→ 16 × 10 = 160 mm

21) 2500 m = _______ km
→ 2500 ÷ 1000 = 2.5 km

22) 65 g = _______ mg
→ 65 × 1000 = 65,000 mg

23) 6.3 cm = _______ mm
→ 6.3 × 10 = 63 mm

24) 120 mg = _______ g
→ 120 ÷ 1000 = 0.12 g

---

Part 3: Compare using <, >, or =

We need to convert both sides to the same unit before comparing.

25) 63 cm _____ 6 m
→ Convert 6 m to cm: 6 × 100 = 600 cm
→ 63 cm < 600 cm → <

26) 536 cm _____ 53.6 dm
→ Convert 53.6 dm to cm: 1 dm = 10 cm → 53.6 × 10 = 536 cm
→ 536 cm = 536 cm → =

27) 5 g _____ 508 mg
→ Convert 5 g to mg: 5 × 1000 = 5000 mg
→ 5000 mg > 508 mg → >

28) 43 mg _____ 5 g
→ Convert 5 g to mg: 5 × 1000 = 5000 mg
→ 43 mg < 5000 mg → <

29) 1,500 mL _____ 1.5 L
→ 1.5 L = 1.5 × 1000 = 1500 mL
→ 1500 mL = 1500 mL → =

30) 3.6 m _____ 36 cm
→ Convert 3.6 m to cm: 3.6 × 100 = 360 cm
→ 360 cm > 36 cm → >
