Final answer:
100 nanometers is equivalent to 0.1 micrometers, as the conversion from nanometers to micrometers requires dividing by 1,000.
Step-by-step explanation:
100 nanometers (nm) is equal to how many micrometers (or microns)? To answer this, we need to apply the unit conversion between nanometers and micrometers. By definition, 1 micrometer (μm) is equal to 1,000 nanometers. Therefore, to convert nanometers to micrometers, we divide the number of nanometers by 1,000.
For the specific question, 100 nm divided by 1,000 equals 0.1 μm. So, 100 nanometers is equivalent to 0.1 micrometers or 0.1 microns.
