How to Convert Sieverts to Kilograys
The sievert and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 1000 sieverts. This means to convert sieverts to kilograys, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 Sv to kilograys:
We need to convert sieverts to kilograys
Since 1 kGy = 1000 Sv, divide by 1000
5 ÷ 1000 = 0.005
5 Sv = 0.005 kGy

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.
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.
