How to convert
Exact conversion factors in both directions, plus a worked example.
1 mrad = 0.001 rad
1 rad = 1000 mrad
To convert millirad to rad, multiply by 0.001.
To convert rad to millirad, multiply by 1000.
Example: convert 10 mrad to rad
10 × 0.001 = 0.01 rad
About these units
Short background on the units used in this conversion.
Rad
The rad equals 0.01 gray — the legacy CGS unit of absorbed dose, still common in US clinical radiology.
Rads label patient dose on older equipment, regulatory limits, and clinical radiography — the most searched absorbed-dose conversion with gray.
Frequently asked questions
How many rads are in one millirad?
One millirad equals 0.001 rads. Multiply your millirads value by 0.001 to convert to rads.
What is the conversion formula?
