About this tool
Convert sieverts to microsieverts instantly. Free, bidirectional, and fully in-browser.
1 sievert equals 1000000 microsieverts — enter any sievert value to convert it to microsieverts instantly. This Sievert to Microsievert converter is a client-side tool: it applies a single multiplication (µSv = Sv × 1000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert microsieverts back to sieverts. A reference table lists common sievert values already converted, and nothing you enter is sent to a server.
Open Sievert to Microsievert Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Sievert field.
Read the equivalent in microsieverts in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert microsieverts to sieverts.
The result updates as you type, and the swap button flips the conversion to microsievert → sievert without reloading.
The conversion uses the precise factor (µSv = Sv × 1000000), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One sievert is 1000000 microsieverts. Multiply the sievert value by 1000000 to convert. For example, 10 Sv = 10000000 µSv.
µSv = Sv × 1000000. This tool applies it automatically and shows a worked example: 10 Sv = 10000000 µSv.
Yes. Press the swap button, or type into the microsievert field, and the tool converts microsieverts to sieverts using the inverse of the same relationship.
It uses the standard radiation dose definition (µSv = Sv × 1000000), not a rounded approximation, so results are exact to the number of decimal places you select.
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.
