Selected category: frequency and angular frequency.
Definition and details for petahertz:
Petahertz (PHz) is a unit of frequency equal to 1015 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.
Definition and details for revolution/hour (rph):
Revolutions per hour (rph) is a unit of frequency, defined as a full rotation around a fixed axis completed in one hour. Rph is equal to 1/60 rpm, or 1/3600 rps.
