How many nanometers are in 82 micrometers?

• A. 820 nanometers
• B. 82,000 nanometers
• C. 0.082 nanometers
• D. 8,200 nanometers

Answer: (B)

Verified step by step guidance

1. Identify the units involved: micrometers (\( \mu m \)) and nanometers (nm).
2. Recall the conversion factors: 1 micrometer (\( 1 \ \mu m \)) equals 1000 nanometers (\( 1000 \ nm \)).
3. Set up the conversion by multiplying the given value in micrometers by the conversion factor: \( 82 \ \mu m \times \frac{1000 \ nm}{1 \ \mu m} \).
4. Perform the multiplication to find the number of nanometers corresponding to 82 micrometers.
5. Express the final answer with the correct units, nanometers (nm).
