📏 Metric Conversions:

#### 1. 6 cm = ___ mm
→ 6 × 10 = 60 mm

#### 2. 80 mm = ___ cm
→ 80 ÷ 10 = 8 cm

#### 3. 14 cm = ___ mm
→ 14 × 10 = 140 mm

#### 4. 7 m = ___ cm
→ 7 × 100 = 700 cm

#### 5. 900 cm = ___ m
→ 900 ÷ 100 = 9 m

#### 6. 3 km = ___ m
→ 3 × 1000 = 3000 m

#### 7. 2000 m = ___ km
→ 2000 ÷ 1000 = 2 km

#### 8. 8.5 km = ___ m
→ 8.5 × 1000 = 8500 m

#### 9. 9650 cm = ___ m
→ 9650 ÷ 100 = 96.5 m

#### 10. 450 mm = ___ cm
→ 450 ÷ 10 = 45 cm

#### 11. 3.5 m = ___ cm
→ 3.5 × 100 = 350 cm

#### 12. 2 m = ___ mm
→ 2 × 100 × 10 = 2 × 1000 = 2000 mm

#### 13. 1 km = ___ m
→ 1 × 1000 = 1000 m

#### 14. 50 m = ___ km
→ 50 ÷ 1000 = 0.05 km

🇺🇸 US Standard Conversions:

#### 15. 2 ft = ___ in
→ 2 × 12 = 24 in

#### 16. 60 in = ___ ft
→ 60 ÷ 12 = 5 ft

#### 17. 10 ft = ___ in
→ 10 × 12 = 120 in

#### 18. 5 yd = ___ ft
→ 5 × 3 = 15 ft

#### 19. 27 ft = ___ yd
→ 27 ÷ 3 = 9 yd

#### 20. 3 mi = ___ yd
→ 3 × 1760 = 5280 yd

#### 21. 8800 yd = ___ mi
→ 8800 ÷ 1760 = 5 mi

#### 22. 2.5 mi = ___ yd
→ 2.5 × 1760 = 4400 yd

#### 23. 51 ft = ___ yd
→ 51 ÷ 3 = 17 yd

#### 24. 198 in = ___ ft
→ 198 ÷ 12 = 16.5 ft

#### 25. 7.5 yd = ___ ft
→ 7.5 × 3 = 22.5 ft

#### 26. 4 yd = ___ in
→ First: 4 yd → ft: 4 × 3 = 12 ft
Then: 12 ft → in: 12 × 12 = 144 in

#### 27. 1.5 mi = ___ yd
→ 1.5 × 1760 = 2640 yd

#### 28. 20 yd = ___ ft
→ 20 × 3 = 60 ft

## 💡 Tips for Future Problems:
- Always check which unit you’re converting from and to.
- Use multiplication when going from larger to smaller units (e.g., km → m).
- Use division when going from smaller to larger units (e.g., cm → m).
- For US units, remember:
→ inches ↔ feet (×12 or ÷12)
→ feet ↔ yards (×3 or ÷3)
→ yards ↔ miles (×1760 or ÷1760)
