What is the metric prefix for 10^-6?

• A. Micro- (µ)
• B. Nano- (n)
• C. Pico- (p)
• D. Milli- (m)

Answer: (A)

In the metric system, prefixes indicate powers of ten. For 10^-6, the prefix is micro, with the symbol µ. One micro unit equals one-millionth of a base unit, so 1 µm is 1×10^-6 meters and 1 µL is 1×10^-6 liters. Nano- corresponds to 10^-9, pico- to 10^-12, and milli- to 10^-3. So these other options represent different, larger or smaller scales than 10^-6. The mnemonic idea is that micro sits between milli (10^-3) and nano (10^-9), reinforcing that it’s specifically 10^-6.
