Enter the number of kilograys that you want to convert to grays.
How to Convert Kilograys to Grays
The kilogray and gray are both units of radiation dose. By definition, 1 kilogray equals exactly 1000 grays. This means to convert kilograys to grays, you multiply by 1000.
Formula
Step-by-Step Example
Convert 5 kGy to grays:
We need to convert kilograys to grays
Since 1 kGy = 1000 Gy, multiply by 1000
5 × 1000 = 5000
5 kGy = 5000 Gy

About These Units
Kilogray (kGy)
A kilogray (kGy) equals 1,000 grays. Used for industrial irradiation: food preservation 1-10 kGy, medical device sterilization 25-50 kGy, cross-linking polymers 50-200 kGy. Far above any biological survivability.
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.
