📏 What’s the Difference Between Kilometers and Nanometers?
oth kilometers (km) and nanometers (nm) are units of length, but they’re on completely different scales.
1 kilometer = 1,000 meters
1 meter = 1,000,000,000 nanometers
So when you combine both:
✅ Conversion Rule:
1 kilometer = 1,000,000,000,000 nanometers
(That’s 1 trillion nanometers!)
📌 Real-Life Examples
Example 1:
You want to convert 3 kilometers to nanometers.
👉 3 × 1,000,000,000,000 = 3,000,000,000,000 nm
Example 2:
The bridge is 0.005 kilometers long.
👉 0.005 × 1,000,000,000,000 = 5,000,000,000 nm
Example 3:
A drone’s flying path covers 12.4 kilometers.
👉 12.4 × 1,000,000,000,000 = 12,400,000,000,000 nm
