Convert 12 Hertz (Hz) to Gigahertz (GHz).

12 Hertz equals 1.200000e-8 Gigahertz. Multiply 12 by 1.000000e-9.

12 Hertz = 1.200000e-8 Gigahertz

Worked example: converting Hertz to Gigahertz

Step 1 — start with the formula. GHz = Hz × 1.000000e-9
Step 2 — substitute your figure. 12 Hz × 1.000000e-9
Step 3 — read the result. 12 Hz = 1.200000e-8 GHz
Step 4 — check it in reverse. Hz = GHz × 1.000000e+9 returns 12 Hz, which matches the figure you started with.

How to Convert Hertz to Gigahertz

To convert from Hertz (Hz) to Gigahertz (GHz), multiply the value by 1.000000e-9.

Formula: GHz = Hz × 1.000000e-9

Reverse: Hz = GHz × 1.000000e+9

Step-by-Step Example

Start with your value in Hertz. For example: 5 Hz
Multiply by the conversion factor: 5 x 1.000000e-9
The result is: 5.000000e-9 GHz

About Hertz

The hertz (Hz) is a unit of frequency. One hertz equals 1 hertz. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: frequency calculations, engineering and science, education.

About Gigahertz

The gigahertz (GHz) is a unit of frequency. One gigahertz equals 1.000000 × 10^+9 hertzs. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
