How to Convert Sieverts to Nanograys
The sievert and nanogray are both units of radiation dose. By definition, 1 sievert equals exactly 1000000000 nanograys. This means to convert sieverts to nanograys, you multiply by 1000000000.
Formula
Step-by-Step Example
Convert 5 Sv to nanograys:
We need to convert sieverts to nanograys
Since 1 Sv = 1000000000 nGy, multiply by 1000000000
5 × 1000000000 = 5000000000
5 Sv = 5000000000 nGy

About These Units
Sievert (Sv)
The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
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.
