About this tool
Hertz to Megahertz Converter
Convert hertz to megahertz instantly. Free, bidirectional, and fully in-browser.
1 hertz equals 1e-6 megahertz — enter any hertz value to convert it to megahertz instantly. This Hertz to Megahertz converter is a client-side tool: it applies a single multiplication (MHz = Hz × 1e-6) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megahertz back to hertz. A reference table lists common hertz values already converted, and nothing you enter is sent to a server.
How to use Hertz to Megahertz Converter

Use the decimal-places slider for more or less precision, or press swap to convert megahertz to hertz.
Why use Hertz to Megahertz Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to megahertz → hertz without reloading.
Exact Frequency math
The conversion uses the precise factor (MHz = Hz × 1e-6), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a hertz measurement to megahertz for a spec, listing, or report.
- Checking hertz↔megahertz figures while comparing products, datasets, or documentation.
- Learning the hertz-to-megahertz relationship from the worked formula and the common-value table.
Frequently asked questions
How many megahertz are in a hertz?
One hertz is 1e-6 megahertz. Multiply the hertz value by 1e-6 to convert. For example, 10 Hz = 1e-5 MHz.
What is the formula to convert hertz to megahertz?
MHz = Hz × 1e-6. This tool applies it automatically and shows a worked example: 10 Hz = 1e-5 MHz.
Can it convert megahertz back to hertz?
Yes. Press the swap button, or type into the megahertz field, and the tool converts megahertz to hertz using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard frequency definition (MHz = Hz × 1e-6), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
