How to Convert Sieverts to Millirads
The sievert and millirad are both units of radiation dose. By definition, 1 sievert equals exactly 100000 millirads. This means to convert sieverts to millirads, you multiply by 100000.
Formula
Step-by-Step Example
Convert 5 Sv to millirads:
We need to convert sieverts to millirads
Since 1 Sv = 100000 mrad, multiply by 100000
5 × 100000 = 500000
5 Sv = 500000 mrad

About These Units
Sievert (Sv)
The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
Millirad (mrad)
A millirad (mrad) equals 0.001 rad or 10 μGy. Used in medical dosimetry: dental bitewing 0.5-2 mrad, chest X-ray 10-20 mrad. Provides convenient scale for diagnostic imaging dose specifications.
