Additional information about this unit converter:

The sievert (Sv) is the SI derived unit of radiation dose. Quantities that are measured in sieverts are designed to represent the stochastic biological effects of ionising radiations. A sievert is a very large unit of dose and often millisieverts (mSv) or microsieverts (μSv) are used.

An older unit of radiation dose, which is still often used in the United States is the roentgen equivalent in man (rem). One Sv is equal to 100 rem. A rem is a large dose of radiation, so the millirem (mrem), which is one thousandth of a rem, is often used for the commonly encountered doses.

The sievert should not be used to express the unmodified absorbed dose of radiation, which is a separate physical quantity measured in grays (Gy). To enable consideration of biological effects, further calculations must be performed to convert absorbed dose into effective dose, the details of which depend on the biological context. This can be far more complicated than just multiplying by a radiation weighting factor and you should consult with a RPA if needing to perform this type of calculation.
