📏 What’s the Difference Between Centimeters and Nanometers?
Both are metric units of length, but they exist on extremely different scales:
A centimeter (cm) is used in daily life — rulers, height, fabric, etc.
A nanometer (nm) is used in science to measure extremely small things like cells, viruses, DNA, and wavelengths of light.
✅ Conversion Rule:
1 centimeter = 10,000,000 nanometers (10 million nm)
📌 Real-Life Examples
Example 1:
You measured a strand of hair that’s 0.005 cm thick.
👉 0.005 × 10,000,000 = 50,000 nm
Example 2:
A microchip component is 1.2 cm long.
👉 1.2 × 10,000,000 = 12,000,000 nm
Example 3:
A lab sample is 0.35 cm in size.
👉 0.35 × 10,000,000 = 3,500,000 nm
