Radiation Equivalent Dose / Sv → rem
Convert Sieverts to Rem
Convert already-weighted equivalent dose in sieverts and rem. Convert Sieverts (Sv) to Rem (rem). Find the formula, worked examples, unit definitions, and practical guidance below.
How to convert sieverts to rem
This converts units of an equivalent dose that has already been determined. It does not infer sieverts from grays or estimate individual health risk. Radiation and tissue weighting are not unit factors.
Use x for the value in Sv, b for the intermediate value in Sv, and y for the result in rem.
rem = Sv ÷ 0.01
Worked examples
10 Sv ≈ 1000 rem
Step 1: (10 × 1) ≈ 10 Sv.
Step 2: 10 ÷ 0.01 ≈ 1000 rem.20 Sv ≈ 2000 rem
Step 1: (20 × 1) ≈ 20 Sv.
Step 2: 20 ÷ 0.01 ≈ 2000 rem.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Sieverts
Sieverts (Sv) measures radiation equivalent dose under the conventions above. The base value in Sv is (x × 1), where x is the numerical value in Sv. Factors shown here are rounded for display; calculations use the stored factor.
About Rem
Rem (rem) measures radiation equivalent dose under the conventions above. The base value in Sv is (x × 0.01), where x is the numerical value in rem. Factors shown here are rounded for display; calculations use the stored factor.
