What this tool does
Convert radiation dose equivalent between sievert, millisievert, microsievert, rem and millirem. Type an amount in sieverts, choose the units, and the tool converts it to rems. It offers 5 radiation dose equivalent units and also shows the same amount in the others.
Inputs
- Value: A number.
- From: Choose one: Sievert, Millisievert, Microsievert, Rem, Millirem. Starts as Sievert.
- To: Choose one of the same 5 units as "From". Starts as Rem.
How to use
- Enter the amount you want to convert.
- Choose the unit to convert from and the unit to convert to.
- Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.
Worked examples
Conversions from sieverts to rems:
- 1 Sv = 100 rem
- 5 Sv = 500 rem
- 10 Sv = 1,000 rem
- 50 Sv = 5,000 rem
- 100 Sv = 10,000 rem
Multiply the number of sieverts by 100 to get rems. Both units are exact definitions, so 100 is the exact factor: 1 Sv = 100 rem.
Sources: Sievert: SI Brochure, 9th edition (2019). Rem: NIST SP 811 (2008), Appendix B.8.
Limitations
- Converts dose equivalent units only. It does not work out a dose from a source or judge whether a dose is safe.
FAQs
- Q: How many rem is one sievert?
- A: One sievert is 100 rem.
- Q: How many millirem is one millisievert?
- A: One millisievert is 100 millirem.
