Question

Express 8.6 km to nanometers

Answer 1

To convert kilometers (km) to nanometers (nm), you can use the following conversion factors:

1 kilometer = \( 1,000 \) meters
1 meter = \( 1,000,000,000 \) nanometers (or \( 10^9 \) nanometers)

Thus, \( 1 \) kilometer = \( 1,000 \times 1,000,000,000 \) nanometers = \( 10^{12} \) nanometers.

Now, to convert \( 8.6 \) kilometers to nanometers:

\[
8.6 \, \text{km} = 8.6 \times 10^{12} \, \text{nanometers} = 8.6 \times 1,000,000,000,000 \, \text{nm}
\]

Calculating this gives:

\[
8.6 \, \text{km} = 8.6 \times 10^{12} \, \text{nm} = 8,600,000,000,000 \, \text{nm}
\]

So, \( 8.6 \, \text{km} \) is equal to \( 8.6 \times 10^{12} \, \text{nanometers} \) or \( 8,600,000,000,000 \, \text{nm} \).
