Which of the following is the metric equivalent to 0.001 liter?

• A. 1 deciliter
• B. 1 milliliter
• C. 1 microliter
• D. 1 centiliter

Answer: (B)

Verified step by step guidance

1. Recall the basic metric prefixes and their corresponding powers of ten relative to the base unit (liter in this case). For example, milli- means \$10^{-3}\(, centi- means \)10^{-2}\(, deci- means \)10^{-1}\(, and micro- means \)10^{-6}$.
2. Express 0.001 liter in terms of powers of ten: \$0.001 \text{ liter} = 1 \times 10^{-3} \text{ liter}$.
3. Match this value to the metric prefix that corresponds to \$10^{-3}\( liters. Since milli- means \)10^{-3}$, 0.001 liter is equivalent to 1 milliliter.
4. Verify the other options by converting their prefixes to liters: 1 deciliter = \$10^{-1}\( liter, 1 centiliter = \)10^{-2}\( liter, and 1 microliter = \)10^{-6}$ liter, which do not match 0.001 liter.
5. Conclude that the metric equivalent to 0.001 liter is 1 milliliter.
