1 kGy (kilograys) = 1000 Sv (sieverts)

How to Convert Kilograys to Sieverts

The kilogray and sievert are both units of radiation dose. By definition, 1 kilogray equals exactly 1000 sieverts. This means to convert kilograys to sieverts, you multiply by 1000.

Formula

sieverts = kilograys × 1000

Step-by-Step Example

Convert 5 kGy to sieverts:

1
Convert 5 kGy to sieverts

We need to convert kilograys to sieverts

2
Apply the formula

Since 1 kGy = 1000 Sv, multiply by 1000

5 × 1000 = 5000

Answer

5 kGy = 5000 Sv

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.

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.
