Convert Microgray to Sievert
Convert micrograys to sieverts by entering a value below.
How to Convert Micrograys to Sieverts
The microgray and sievert are both units of radiation dose. By definition, 1 sievert equals exactly 1000000 micrograys. This means to convert micrograys to sieverts, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 μGy to sieverts:
We need to convert micrograys to sieverts
Since 1 Sv = 1000000 μGy, divide by 1000000
5 ÷ 1000000 = 5e-6
5 μGy = 5e-6 Sv

About These Units
Microgray (μGy)
A microgray (μGy) equals 0.001 mGy or 0.1 mrad. Chest X-ray: ~20 μGy. Panoramic dental X-ray: 10-20 μGy. Used for specifying doses from diagnostic imaging with minimal exposure. One gray = one million micrograys.
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.
