Enter the number of millirem that you want to convert to nanograys.
How to Convert Millirem to Nanograys
The millirem and nanogray are both units of radiation dose. By definition, 1 millirem equals exactly 10000 nanograys. This means to convert millirem to nanograys, you multiply by 10000.
Formula
Step-by-Step Example
Convert 5 mrem to nanograys:
We need to convert millirem to nanograys
Since 1 mrem = 10000 nGy, multiply by 10000
5 × 10000 = 50000
5 mrem = 50000 nGy

About These Units
Millirem (mrem)
A millirem (mrem) equals 0.001 rem or 10 μSv. US dosimetry standard: natural background 300-400 mrem/year, occupational limit 5,000 mrem/year, public limit 100 mrem/year above background. Chest X-ray: ~2 mrem.
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.
