About this tool

The equivalent dose expresses the biological effect of radiation in sieverts (often millisieverts or microsieverts); in the US the rem is still used.

Here every value is converted through the sievert (Sv). Choose any two of the 5 units below the converter, or start from one of the popular conversions.
