milligray to nanogray
Convert milligray (mGy) to nanogray (nGy). Use an editable absorbed dose converter, conversion formula, and reference table.
1 mGy = 1,000,000 nGy
Conversion formula
One milligray equals 1,000,000 nanogray. Multiply your value in milligray by this factor to get nanogray. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 milligray:5 × 1,000,000 = 5,000,000 nGy

About these measurements
Absorbed dose measures energy deposited per unit mass.
The base reference used here is the gray. One milligray is 0.001 base units; one nanogray is 1e-9 base units.
Important distinctions
Physical unit conversion only. Biological effect requires additional information and professional assessment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mGy to nGy?
Multiply the quantity in mGy by 1,000,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanogray to milligray converter.
