GHz to ns Converter

This tool calculates nanosecond (ns) from the frequency in Giga Hertz (GHz).

Enter the frequency in GHz.

🔁 ns to GHz


The period T is the inverse of frequency f

T (seconds) = 1/f (Hz)

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

T (nanoseconds) = 1/f (GHz)

What is a Nanosecond?

A nanosecond (ns) is a unit of time equal to one billionth of a second, or (10-9) seconds. The term comes from the prefix “nano-“, which means one billionth.

Comparison to Other Units of Time

  • Microsecond: 1 microsecond (µs) = 1,000 nanoseconds
  • Millisecond: 1 millisecond (ms) = 1,000,000 nanoseconds
  • Second: 1 second (s) = 1,000,000,000 nanoseconds

Applications and Significance

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

  • Electronics and Computing: The speed of processors and the time it takes for electrical signals to travel through circuits are often measured in nanoseconds. For example, modern computer processors can have clock speeds of several gigahertz (GHz), meaning they can perform billions of cycles per second, with each cycle taking only a few nanoseconds.
  • Telecommunications: Data transmission speeds and latency in networks are frequently measured in nanoseconds.
  • Physics and Chemistry: Many processes at the atomic and molecular levels occur on the nanosecond timescale, making it an important unit of measure in these fields.


To help visualize how short a nanosecond is:

  • Light travels approximately 30 centimeters (about 1 foot) in one nanosecond.
  • A nanosecond is to one second as one second is to about 31.7 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.
