Convert Nanogray to Rem
Convert nanograys to rem by entering a value below.
How to Convert Nanograys to Rem
The nanogray and rem are both units of radiation dose. By definition, 1 rem equals exactly 10000000 nanograys. This means to convert nanograys to rem, you divide by 10000000.
Formula
Step-by-Step Example
Convert 5 nGy to rem:
We need to convert nanograys to rem
Since 1 rem = 10000000 nGy, divide by 10000000
5 ÷ 10000000 = 5e-7
5 nGy = 5e-7 rem

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.
Rem (rem)
The rem (Roentgen Equivalent Man) is the traditional unit of equivalent dose. One sievert = 100 rem exactly. Still used in US nuclear industry and regulations. Annual occupational limit: 5 rem/year. Natural background: 0.3 rem/year. Acute 450 rem ≈ LD50.
