How to convert rems to millirems

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.

Formula
mrem = rem × 2000/2

One rem is 2000/2 millirems, so a single multiplication converts any value.

Example
10,000 mrem = 10 × 2000/2

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.
