What is a petahertz (PHz)?

A petahertz is a unit of frequency equal to 10^15 hertz used to measure very high oscillation rates such as in ultrafast optics.

In what situations is converting from petahertz to millihertz useful?

This conversion is helpful to connect ultrafast high-frequency phenomena with very low-frequency events, aiding analysis across a broad spectrum.

Why might large numbers result from this conversion?

Because petahertz and millihertz differ by 10^18, converting between them generates very large values requiring careful computation.
