How to Convert Sievert to Rem
- 1 Sv = 100 rem
- 1 rem = 0.01 Sv
- Example: convert 1 Sv to rem: 1 Sv = 1 × 100 rem = 100 rem
Formula
rem = Sv × 100
Derivation from SI units:
- 1 Sv = 1 J/kg weighted for radiation type (and tissue for effective dose).
- 1 rem = 0.01 Sv.
Both units are defined exactly, so the factor is exact. Sievert definition: sievert; Rem definition: rem.
Worked examples
- 1 Sv is 100 rem.
1 Sv × 100 = 100 rem - An annual dose of 0.05 Sv is 5 rem.
0.05 Sv × 100 = 5 rem
