Convert Gray to Nanosievert
Enter the number of grays that you want to convert to nanosieverts.
How to Convert Grays to Nanosieverts
The gray and nanosievert are both units of radiation dose. By definition, 1 gray equals exactly 1000000000 nanosieverts. This means to convert grays to nanosieverts, you multiply by 1000000000.
Formula
Step-by-Step Example
Convert 5 Gy to nanosieverts:
We need to convert grays to nanosieverts
Since 1 Gy = 1000000000 nSv, multiply by 1000000000
5 × 1000000000 = 5000000000
5 Gy = 5000000000 nSv

About These Units
Gray (Gy)
The gray (Gy) is the SI unit of absorbed dose: energy deposited per unit mass (1 Gy = 1 J/kg). Named after Louis Harold Gray. For gamma/X-rays and beta particles, 1 Gy ≈ 1 Sv (quality factor Q=1). Radiation therapy total dose: 40-80 Gy.
Nanosievert (nSv)
A nanosievert (nSv) equals 10⁻⁹ sieverts or 0.001 μSv. Used for extremely low radiation levels in environmental monitoring, clean room specifications, and background radiation surveys. Natural background: ~200-300 nSv/h typical.
