Hertz to Megahertz formula

MHz = Hz ÷ 1,000,000

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

Worked examples

2 hertz = 0.000002 megahertz — 2 ÷ 1,000,000 = 0.000002 megahertz
6 hertz = 0.000006 megahertz — 6 ÷ 1,000,000 = 0.000006 megahertz
10 hertz = 0.00001 megahertz — 10 ÷ 1,000,000 = 0.00001 megahertz

When you need to convert hertz 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 hertz = 0.000001 megahertz, the answer should be smaller 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

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.
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.
