📏 Micrometers vs. Millimeters – What’s the Difference?
Both are part of the metric system, but they differ in scale:
1 millimeter (mm) = 1,000 micrometers (µm)
So,
👉 1 micrometer = 0.001 millimeters
📌 Real-Life Examples
Example 1:
Convert 5,000 µm into mm
👉 5,000 ÷ 1,000 = 5 mm
Example 2:
A microchip layer is 750 µm thick
👉 750 ÷ 1,000 = 0.75 mm
Example 3:
A hair strand is 100 µm wide
👉 100 ÷ 1,000 = 0.1 mm
🧮 Quick Conversion Table
Micrometers (µm) | Millimeters (mm) |
