Convert **petahertz** to **degree/hour**

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.

Degree per hour (deg/hr) is a unit of angular frequency equal to 1/(360x3600) Hz, or 1/(360x3600) rps. Angular frequency, or angular speed is the magnitude of the vector quantity angular velocity.

Swap, do a degree/hour to petahertz conversion.
