What is the prefix, symbol, and meaning of the exponent 10 to the -6th power?

Explanation:
The concept here is how SI prefixes map to powers of ten. A exponent of -6 corresponds to the prefix micro, with the standard symbol μ, and it means one millionth. So 1 μ (one micro) equals 1 × 10^-6, which is 0.000001. The micro prefix comes from Greek mikros meaning small, and μ is the official symbol. In ASCII contexts you might see 'u' used, but the correct symbol is μ. The other options would pair the wrong exponent or use an alternative symbol: nano is 10^-9 (billionth), milli is 10^-3 (thousandth).
