How to convert millisieverts to rems
Sieverts and rem express weighted radiation dose: 1 rem = 0.01 Sv. This page changes units only; it does not determine weighting factors, effective dose or health risk from an absorbed dose.
rem = mSv × 1/10One millisievert is 1/10 rems, so a single multiplication converts any value.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
