Exact conversion factors in both directions, plus a worked example.
1 rad = 1000 mrad
1 mrad = 0.001 rad
To convert rad to millirad, multiply by 1000.
To convert millirad to rad, multiply by 0.001.
Example: convert 10 rad to mrad
10 × 1000 = 10000 mrad
Short background on the units used in this conversion.
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.
The millirad (mrad) equals 0.001 rad or 10 microgray — a small absorbed-dose increment.
mrads quantify low-level occupational and environmental absorbed doses in legacy US reporting.
mrad = rad × 1,000rad = mrad × 0.001, using the same exact factors as this converter.
