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

Answer: (A)

Verified step by step guidance

1. Understand the prefix 'micro-' in the metric system, which denotes a factor of \$10^{-6}$.
2. Recall that 1 micrometer (symbol: \(\mu m\)) is defined as \$1 \times 10^{-6}$ meters.
3. 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.
4. Identify that the value equal to 1 micrometer must be \$1 \times 10^{-6}$ meters based on the metric prefix.
5. Conclude that the correct choice is the one that matches \$1 \times 10^{-6}$ meters.
