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

rads = millisieverts ÷ 10

Step-by-Step Example

Convert 5 mSv to rads:

1
Convert 5 mSv to rads

We need to convert millisieverts to rads

2
Apply the formula

Since 1 rad = 10 mSv, divide by 10

5 ÷ 10 = 0.5

Answer

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.
