What is 1 gigahertz in megahertz?
1 gigahertz is equal to exactly 1,000 megahertz.
1 × 1,000 = 1,000 megahertz
Result
1 gigahertz = 1,000 megahertz
Gigahertz to Megahertz formula
MHz = GHz × 1,000
The gigahertz to megahertz conversion factor is 1,000, which is exact by definition. 1 gigahertz = 1,000 megahertz, and 1 megahertz = 0.001 gigahertz.
Worked examples
- 2 gigahertz = 2,000 megahertz — 2 × 1,000 = 2,000 megahertz
- 6 gigahertz = 6,000 megahertz — 6 × 1,000 = 6,000 megahertz
- 10 gigahertz = 10,000 megahertz — 10 × 1,000 = 10,000 megahertz

When you need to convert gigahertz to megahertz
- 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 gigahertz = 1,000 megahertz, the answer should be larger 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
- 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.
- Megahertz (MHz): One million cycles per second. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
