About radiology: equivalent dose conversions
Equivalent dose (sievert, rem) weights absorbed dose by radiation type. This is a unit converter, not medical or safety advice.

| Unit | System | Definition and notes |
|---|---|---|
| Sievert (Sv) | SI (metric) | Base unit |
| Millisievert (mSv) | SI (metric) | 1 mSv = 0.001 Sv (exact) |

Frequently asked questions
Which radiology: equivalent dose units can I convert?
sieverts (Sv), millisieverts (mSv), microsieverts (µSv), rem (rem), millirem (mrem).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
