Use the Radiation Dose Equivalent Converter
Radiation Dose Equivalent formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in Sv.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (Sv) |
Radiation Dose Equivalent examples
Sv to mSv
10 Sv = 10,000 mSv.
Sv to µSv
10 Sv = 10,000,000 µSv.
Sv to rem
10 Sv = 1,000 rem.
How to calculate Radiation Dose Equivalent step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Radiation Dose Equivalent result
Dose equivalent weights absorbed dose by the type of radiation. The SI unit is the sievert. One rem is exactly 0.01 Sv, so 1 Sv is 100 rem. Natural background radiation averages roughly 2 to 3 mSv per year worldwide.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 SV |
|---|---|---|---|
| Sievert | Sv | 1 Sv = 1 Sv | 1 Sv |
| Millisievert | mSv | 1 mSv = 0.001 Sv | 1,000 mSv |
| Microsievert | µSv | 1 µSv = 0.000001 Sv | 1,000,000 µSv |
| Rem | rem | 1 rem = 0.01 Sv | 100 rem |
| Millirem | mrem | 1 mrem = 0.00001 Sv | 100,000 mrem |
Common mistakes when calculating Radiation Dose Equivalent
- Confusing the sievert (biological effect) with the gray (energy absorbed).
- Mixing mSv and µSv, which differ by 1,000.
- Mixing rem and mrem, which differ by 1,000.
Radiation Dose Equivalent FAQ
How many rem is 1 Sv?
1 Sv is 100 rem.
How many µSv is 1 mSv?
1 mSv is 1,000 µSv.
How many mrem is 1 mSv?
1 mSv is 100 mrem.
What is the base unit for radiation dose equivalent?
This converter uses sievert (Sv) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two radiation dose equivalent units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many millisieverts are in 1 sievert?
1 Sv = 1,000 mSv.
How many microsieverts are in 1 sievert?
1 Sv = 1,000,000 µSv.
How many rems are in 1 sievert?
1 Sv = 100 rem.
Which radiation dose equivalent units does this converter support?
It covers 5 units: sievert (Sv), millisievert (mSv), microsievert (µSv), rem (rem), millirem (mrem).
How accurate is the radiation dose equivalent converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
