How many hertz are in one gigahertz?

There are 1,000,000,000 hertz in 1 gigahertz.

How do you convert hertz to gigahertz?

Multiply the number of hertz by 1 × 10⁻⁹ — or use the formula GHz = Hz ÷ 1,000,000,000.

What is 6 hertz in gigahertz?

6 hertz is 6 × 10⁻⁹ gigahertz. 6 ÷ 1,000,000,000 = 6 × 10⁻⁹ gigahertz.

Is the hertz to gigahertz conversion exact?

Yes. The relationship is fixed by definition, so 1 × 10⁻⁹ is an exact conversion factor — only the displayed result is rounded.

Hertz to Gigahertz formula

GHz = Hz ÷ 1,000,000,000

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

Worked examples

2 hertz = 2 × 10⁻⁹ gigahertz — 2 ÷ 1,000,000,000 = 2 × 10⁻⁹ gigahertz
6 hertz = 6 × 10⁻⁹ gigahertz — 6 ÷ 1,000,000,000 = 6 × 10⁻⁹ gigahertz
10 hertz = 1 × 10⁻⁸ gigahertz — 10 ÷ 1,000,000,000 = 1 × 10⁻⁸ gigahertz

When you need to convert hertz to gigahertz

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 hertz = 1 × 10⁻⁹ gigahertz, the answer should be smaller 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

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.
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.
