How many nanometers are in 82 micrometers?
A
820 nanometers
B
82,000 nanometers
C
0.082 nanometers
D
8,200 nanometers
Verified step by step guidance1
Identify the units involved: micrometers (\( \mu m \)) and nanometers (nm).
Recall the conversion factors: 1 micrometer (\( 1 \ \mu m \)) equals 1000 nanometers (\( 1000 \ nm \)).
Set up the conversion by multiplying the given value in micrometers by the conversion factor: \( 82 \ \mu m \times \frac{1000 \ nm}{1 \ \mu m} \).
Perform the multiplication to find the number of nanometers corresponding to 82 micrometers.
Express the final answer with the correct units, nanometers (nm).
