📏 Kilometers vs. Millimeters – What’s the Difference?
Both are metric units of length, but they sit on opposite ends of the scale:
1 kilometer (km) = 1,000 meters
1 meter = 1,000 millimeters
So,
👉 1 kilometer = 1,000,000 millimeters
Yes — that’s 1 million millimeters in a single kilometer!
📌 Real-Life Examples
Example 1:
You want to convert 3.5 km into mm.
👉 3.5 × 1,000,000 = 3,500,000 mm
Example 2:
A road is 0.75 km long.
👉 0.75 × 1,000,000 = 750,000 mm
Example 3:
Your drone flew 1.2 km.
👉 1.2 × 1,000,000 = 1,200,000 mm
