Convert Petahertz to Megahertz

A Petahertz (PHz) is a unit of frequency equal to one quadrillion hertz (1,000,000,000,000,000 Hz). Frequency measures how often an event occurs over a set period, and in the case of petahertz, it refers to one quadrillion cycles per second.

Understanding Frequency Units

Frequency is a key concept in various fields, such as physics, engineering, and communication. It's commonly expressed in hertz (Hz) and its multiples:

• 1 hertz (Hz) = 1 cycle per second
• 1 kilohertz (kHz) = 1,000 cycles per second
• 1 megahertz (MHz) = 1,000,000 cycles per second
• 1 gigahertz (GHz) = 1,000,000,000 cycles per second
• 1 terahertz (THz) = 1,000,000,000,000 cycles per second
• 1 petahertz (PHz) = 1,000,000,000,000,000 cycles per second
