Ohm to Megohm Converter
Convert ohms to megohms instantly. Free, bidirectional, and fully in-browser.
1 ohm equals 1e-6 megohms — enter any ohm value to convert it to megohms instantly. This Ohm to Megohm converter is a client-side tool: it applies a single multiplication (MΩ = Ω × 1e-6) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megohms back to ohms. A reference table lists common ohm values already converted, and nothing you enter is sent to a server.
How to use Ohm to Megohm Converter
- 1
Open Ohm to Megohm Converter on AltFTool — it loads instantly in your browser.
- 2
Type the value you want to convert into the Ohm field.
- 3
Read the equivalent in megohms in the result field, and copy it if needed.
- 4
Use the decimal-places slider for more or less precision, or press swap to convert megohms to ohms.
Why use Ohm to Megohm Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to megohm → ohm without reloading.
Exact Electrical Resistance math
The conversion uses the precise factor (MΩ = Ω × 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 an ohm measurement to megohms for a spec, listing, or report.
- Checking ohm↔megohm figures while comparing products, datasets, or documentation.
- Learning the ohm-to-megohm relationship from the worked formula and the common-value table.
Frequently asked questions
How many megohms are in an ohm?
One ohm is 1e-6 megohms. Multiply the ohm value by 1e-6 to convert. For example, 10 Ω = 1e-5 MΩ.
What is the formula to convert ohms to megohms?
MΩ = Ω × 1e-6. This tool applies it automatically and shows a worked example: 10 Ω = 1e-5 MΩ.
Can it convert megohms back to ohms?
Yes. Press the swap button, or type into the megohm field, and the tool converts megohms to ohms using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard electrical resistance definition (MΩ = Ω × 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.
