Gigahertz to Megahertz Converter
1 gigahertz = 1,000 megahertz
1 gigahertz equals 1,000 megahertz
How to convert gigahertz to megahertz
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.
MHz = GHz × 1000One gigahertz is 1000 megahertz, so a single multiplication converts any value.
10,000 MHz = 10 × 1000Gigahertz to megahertz conversion table

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.
