📏 What’s the Difference Between Centimeters and Kilometers?
Both centimeters (cm) and kilometers (km) are units from the metric system — but they sit on opposite ends of the scale:
1 kilometer = 1,000 meters
1 meter = 100 centimeters
So,
👉 1 kilometer = 100,000 centimeters
✅ Conversion Rule:
1 centimeter = 0.00001 kilometers
📌 Real-Life Examples
Example 1:
You have 120,000 cm of electric wire.
👉 120,000 ÷ 100,000 = 1.2 kilometers
Example 2:
Your cloth roll is 45,000 cm long.
👉 45,000 ÷ 100,000 = 0.45 km
Example 3:
A toy train track measures 750,000 cm.
👉 750,000 ÷ 100,000 = 7.5 kilometers
🧮 Quick Conversion Table
| Centimeters (cm) | Kilometers (km) |
