Which of the following values is equal to 1 micrometer?
A
1 × 10^{-6} meters
B
1 × 10^{-3} meters
C
1 × 10^{-12} meters
D
1 × 10^{-9} meters
Verified step by step guidance1
Understand the prefix 'micro-' in the metric system, which denotes a factor of \$10^{-6}$.
Recall that 1 micrometer (symbol: \(\mu m\)) is defined as \(1 \times 10^{-6}\) meters.
Compare the given options to this definition: \(1 \times 10^{-3}\) meters is a millimeter, \(1 \times 10^{-9}\) meters is a nanometer, and \(1 \times 10^{-12}\) meters is a picometer.
Identify that the value equal to 1 micrometer must be \(1 \times 10^{-6}\) meters based on the metric prefix.
Conclude that the correct choice is the one that matches \(1 \times 10^{-6}\) meters.
