Convert Millirad to Nanogray
Input the number of millirads you want to convert to nanograys.
How to Convert Millirads to Nanograys
The millirad and nanogray are both units of radiation dose. By definition, 1 millirad equals exactly 10000 nanograys. This means to convert millirads to nanograys, you multiply by 10000.
Formula
Step-by-Step Example
Convert 5 mrad to nanograys:
We need to convert millirads to nanograys
Since 1 mrad = 10000 nGy, multiply by 10000
5 × 10000 = 50000
5 mrad = 50000 nGy

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.
Nanogray (nGy)
A nanogray (nGy) equals 10⁻⁹ grays. Used in background radiation measurements and environmental monitoring. Natural background dose rate: 50-200 nGy/h from cosmic rays and terrestrial sources. Sensitive dosimeters measure in nGy.
