Convert Nanogray to Milligray
Type the number of nanograys that you wish to convert to milligrays.
How to Convert Nanograys to Milligrays
The nanogray and milligray are both units of radiation dose. By definition, 1 milligray equals exactly 1000000 nanograys. This means to convert nanograys to milligrays, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 nGy to milligrays:
We need to convert nanograys to milligrays
Since 1 mGy = 1000000 nGy, divide by 1000000
5 ÷ 1000000 = 5e-6
5 nGy = 5e-6 mGy

About These Units
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.
Milligray (mGy)
A milligray (mGy) equals 0.001 gray or 0.1 rad. Common medical imaging doses: CT scan 10-30 mGy, mammogram 2-3 mGy, fluoroscopy 20-50 mGy. Diagnostic reference levels often specified in mGy.
