Convert Microsievert to Sievert

Input the number of microsieverts you want to convert to sieverts.

1 μSv (microsieverts) = 1e-6 Sv (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

sieverts = microsieverts ÷ 1000000

Step-by-Step Example

Convert 5 μSv to sieverts:

1
Convert 5 μSv to sieverts

We need to convert microsieverts to sieverts

2
Apply the formula

Since 1 Sv = 1000000 μSv, divide by 1000000

5 ÷ 1000000 = 5e-6

Answer

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.
