Convert Millirad to Rad
Type the number of millirads that you wish to convert to rads.
How to Convert Millirads to Rads
The millirad and rad are both units of radiation dose. By definition, 1 rad equals exactly 1000 millirads. This means to convert millirads to rads, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 mrad to rads:
We need to convert millirads to rads
Since 1 rad = 1000 mrad, divide by 1000
5 ÷ 1000 = 0.005
5 mrad = 0.005 rad

About These Units
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.
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.
