Hertz to Gigahertz Converter
1 hertz = 1e-9 gigahertz
1 hertz equals 1e-9 gigahertz
How to convert hertz to gigahertz
Hertz counts complete cycles per second. This converter treats one revolution as one cycle, so 60 rpm = 1 Hz; angular frequency in radians per second would additionally involve 2π.
GHz = Hz ÷ 1000000000One gigahertz corresponds to 1000000000 hertz, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

gigahertzGHz
One billion hertz. Used for processor and Wi-Fi frequencies.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
