The value of one angstrom (Å) can be expressed in micrometers as:

1. 1Å equals 10⁻¹⁰ meters
2. 1Å equals 10⁻⁸ centimeters
3. 1Å equals 10⁻⁷ millimeters
4. 1Å equals 10⁻⁴ micrometers

Correct answer: 1Å equals 10⁻⁴ micrometers

Solution

An angstrom is 10⁻¹⁰ meters. Since 1 micrometer is 10⁻⁶ meters, dividing gives 10⁻¹⁰ ÷ 10⁻⁶ = 10⁻⁴ micrometers.
