Verified step by step guidance

1. Understand that metric prefixes represent specific powers of ten, which help express quantities in more manageable units.
2. Recall that the prefix 'deci-' corresponds to a factor of \$10^{-1}$, which is 0.1.
3. Recall that the prefix 'centi-' corresponds to a factor of \$10^{-2}$, which is 0.01.
4. Recall that the prefix 'milli-' corresponds to a factor of \$10^{-3}$, which is 0.001 or one-thousandth.
5. Recall that the prefix 'micro-' corresponds to a factor of \$10^{-6}$, which is 0.000001.
