Convert **petahertz** to **centihertz**

Selected category: frequency and angular frequency.

Petahertz (PHz) is a unit of frequency equal to 10^{15} Hz. For example 2.47 PHz is the frequency of Lyman-alpha line, a spectral line of hydrogen, which is emitted when the electron falls from the n = 2 orbital to the n = 1 orbital.

Centihertz (cHz) is a unit of frequency equal to 0.01 Hz.
