What is 1 gigahertz in hertz?

1 gigahertz is equal to exactly 1,000,000,000 hertz.

1 × 1,000,000,000 = 1,000,000,000 hertz

Result1,000,000,000

1 gigahertz = 1,000,000,000 hertz

Gigahertz to Hertz formula

Hz = GHz × 1,000,000,000

The gigahertz to hertz conversion factor is 1,000,000,000, which is exact by definition. 1 gigahertz = 1,000,000,000 hertz, and 1 hertz = 1 × 10⁻⁹ gigahertz.

Worked examples

  • 2 gigahertz = 2,000,000,000 hertz — 2 × 1,000,000,000 = 2,000,000,000 hertz
  • 6 gigahertz = 6,000,000,000 hertz — 6 × 1,000,000,000 = 6,000,000,000 hertz
  • 10 gigahertz = 10,000,000,000 hertz — 10 × 1,000,000,000 = 10,000,000,000 hertz

When you need to convert gigahertz to hertz

  • Comparing specifications written for a different market.
  • Checking a figure quoted in an unfamiliar unit before acting on it.
  • Converting values consistently across a spreadsheet, report or shopping list.

Common mistakes to avoid

  • Dividing when you should multiply. Because 1 gigahertz = 1,000,000,000 hertz, the answer should be larger than the number you started with.
  • Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

  • Gigahertz (GHz): One billion cycles per second; CPU and radio frequencies. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
  • Hertz (Hz): One cycle per second; the SI unit of frequency. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.

Frequently asked questions

What is 1 gigahertz in hertz?
1 gigahertz is equal to 1,000,000,000 hertz.
How many gigahertz are in one hertz?
There are 1 × 10⁻⁹ gigahertz in 1 hertz.
How do you convert gigahertz to hertz?
Multiply the number of gigahertz by 1,000,000,000 — or use the formula Hz = GHz × 1,000,000,000.
What is 6 gigahertz in hertz?
6 gigahertz is 6,000,000,000 hertz. 6 × 1,000,000,000 = 6,000,000,000 hertz.
Is the gigahertz to hertz conversion exact?
Yes. The relationship is fixed by definition, so 1,000,000,000 is an exact conversion factor — only the displayed result is rounded.
