GHz to ps Conversion Calculator

This tool calculates picosecond (ps) from the frequency in Giga Hertz (GHz).


Enter the frequency in GHz.

🔁 ps to GHz


The period T is the inverse of frequency f

T (seconds) = 1/f (Hz)

T (seconds) = [1/f (GHz)]*10-9

1 second = 1012 picoseconds

T (picoseconds) = 1000/f (GHz)

Example Calculations

  • 1 GHz is equivalent to 1000 ps
  • 2 GHz is equivalent to 500 ps

What is a Picosecond?

A picosecond (ps) is a unit of time equal to one trillionth of a second, or 10-12 seconds. The prefix “pico-” denotes a factor of 10^-12, making a picosecond an extremely short duration.

Comparison to Other Units of Time

  • Nanosecond (ns): 1 nanosecond = 1,000 picoseconds
  • Microsecond (µs): 1 microsecond = 1,000,000 picoseconds
  • Millisecond (ms): 1 millisecond = 1,000,000,000 picoseconds
  • Second (s): 1 second = 1,000,000,000,000 picoseconds

Applications and Significance

Picoseconds are used in various scientific and technological fields where very short time intervals need to be measured or specified, such as:

Physics and Chemistry

  • Laser Physics: The duration of ultra-short laser pulses is often measured in picoseconds. These ultra-fast pulses are used in various applications, including spectroscopy and material processing.
  • Molecular Dynamics: Many processes at the atomic and molecular levels occur on the picosecond timescale. This is important in the study of chemical reactions and the behavior of molecules.

Electronics and Computing

  • High-Speed Circuits: The operation of high-speed digital circuits, including signal propagation delays, can be measured in picoseconds. This is crucial for the design of fast processors and communication devices.
  • Signal Processing: High-frequency signals in advanced communication systems can have components that oscillate with picosecond periods.


  • Data Transmission: In optical fiber communications, data transmission rates can reach speeds where individual bits of information are separated by picoseconds.


To help visualize how short a picosecond is:

  • Light Travel: Light travels approximately 0.3 millimeters (about 0.012 inches) in one picosecond.
  • Comparison: A picosecond is to one second as one second is to about 31.7 million years.

What is a GHz?

A gigahertz (GHz) is a unit of frequency equivalent to one billion hertz (Hz). The term “hertz” represents one cycle per second, so a gigahertz signifies one billion cycles per second. The prefix “giga-” means one billion (10^9).

Applications and Significance

  • Processor Speeds: The clock speed of computer processors is commonly measured in gigahertz. A 3 GHz processor, for example, can perform 3 billion cycles per second.
  • Data Transfer Rates: High-speed data transfer technologies, such as those used in computer networks and telecommunications, often use frequencies measured in gigahertz.


  • Wireless Communication: Many wireless communication systems, including Wi-Fi, Bluetooth, and cellular networks, operate at frequencies in the gigahertz range. For example, Wi-Fi typically operates at 2.4 GHz or 5 GHz.
  • Satellite Communications: Satellite communication frequencies also fall within the gigahertz range, allowing for high-speed data transmission over long distances.

Radio and Television Broadcasting

  • Microwave Frequencies: Frequencies in the gigahertz range are used for microwave transmissions, including some radio and television broadcasts.

Comparison to Other Units of Frequency

  • Kilohertz (kHz): 1 kHz = 1,000 Hz
  • Megahertz (MHz): 1 MHz = 1,000,000 Hz or 1,000 kHz
  • Gigahertz (GHz): 1 GHz = 1,000,000,000 Hz or 1,000 MHz


To understand how fast a gigahertz is:

  • 1 GHz represents one billion cycles per second.
  • If you could count one billion cycles at the rate of one cycle per second, it would take you about 31.7 years to reach one billion.

In summary, gigahertz is a unit of frequency widely used in various technological and scientific fields to denote very high-speed cycles or oscillations, particularly in computing, telecommunications, and broadcasting.
