How many megahertz are in one hertz?

There are 0.000001 megahertz in 1 hertz.

How do you convert megahertz to hertz?

Multiply the number of megahertz by 1,000,000 — or use the formula Hz = MHz × 1,000,000.

What is 6 megahertz in hertz?

6 megahertz is 6,000,000 hertz. 6 × 1,000,000 = 6,000,000 hertz.

Is the megahertz to hertz conversion exact?

Yes. The relationship is fixed by definition, so 1,000,000 is an exact conversion factor — only the displayed result is rounded.

Megahertz to Hertz formula

Hz = MHz × 1,000,000

The megahertz to hertz conversion factor is 1,000,000, which is exact by definition. 1 megahertz = 1,000,000 hertz, and 1 hertz = 0.000001 megahertz.

Worked examples

2 megahertz = 2,000,000 hertz — 2 × 1,000,000 = 2,000,000 hertz
6 megahertz = 6,000,000 hertz — 6 × 1,000,000 = 6,000,000 hertz
10 megahertz = 10,000,000 hertz — 10 × 1,000,000 = 10,000,000 hertz

When you need to convert megahertz to hertz

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 megahertz = 1,000,000 hertz, 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

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.
Hertz (Hz): One cycle per second; the SI unit of frequency. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
