A nanometer is equivalent to which of the following?

In the metric system, the nano- prefix means 10^-9, so a nanometer is 1 x 10^-9 meters. That makes it one-billionth of a meter. The other options represent different powers of ten: a trillionth of a meter is 10^-12, a millionth of a meter is 10^-6, and a full meter is 1. Nanometers are commonly used to measure atoms, molecules, and wavelengths of light (for example, visible light wavelengths are hundreds of nanometers, and 1 nm equals 0.001 micrometers).
