Megahertz to Gigahertz Converter
1 megahertz = 0.001 gigahertz
1 megahertz equals 0.001 gigahertz
How to convert megahertz 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 = MHz × 0.001One megahertz is 0.001 gigahertz, so a single multiplication converts any value.
0.01 GHz = 10 × 0.001Megahertz to gigahertz 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.
