How to Convert Millisieverts to Rads
The millisievert and rad are both units of radiation dose. By definition, 1 rad equals exactly 10 millisieverts. This means to convert millisieverts to rads, you divide by 10.
Formula
Step-by-Step Example
Convert 5 mSv to rads:
We need to convert millisieverts to rads
Since 1 rad = 10 mSv, divide by 10
5 ÷ 10 = 0.5
5 mSv = 0.5 rad

About These Units
Millisievert (mSv)
A millisievert (mSv) equals 0.001 sieverts or 100 mrem. Natural background: 2-3 mSv/year. CT scan: 2-15 mSv. Annual occupational limit: 20-50 mSv (varies by country). Single dose above 100 mSv increases cancer risk slightly.
Rad (rad)
The rad (Radiation Absorbed Dose) is the traditional unit of absorbed dose. One gray = 100 rads exactly. One rad = 100 ergs/gram = 0.01 J/kg. Still used in US medical and nuclear industries. One rad = one centigray = one rem for gamma/X-rays.
