Convert Microsievert to Sievert
Input the number of microsieverts you want to convert to sieverts.
How to Convert Microsieverts to Sieverts
The microsievert and sievert are both units of radiation dose. By definition, 1 sievert equals exactly 1000000 microsieverts. This means to convert microsieverts to sieverts, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 μSv to sieverts:
We need to convert microsieverts to sieverts
Since 1 Sv = 1000000 μSv, divide by 1000000
5 ÷ 1000000 = 5e-6
5 μSv = 5e-6 Sv

About These Units
Microsievert (μSv)
A microsievert (μSv) equals 0.001 mSv or 0.1 mrem. Common exposures: dental X-ray ~5 μSv, chest X-ray 20 μSv, transatlantic flight 40-80 μSv, banana (K-40) 0.1 μSv. Most radiation meters display μSv/h for environmental monitoring.
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.
