About these units
The sievert (Sv) is an SI base or derived unit of radiation dose.
The millisievert (mSv) is a metric unit of radiation dose, equal to 0.001 sieverts.
Going the other way, 1 millisievert = 0.001 sieverts. Absorbed dose is measured in grays (or rads); equivalent dose, which accounts for biological effect, is measured in sieverts (or rems). For X-rays, gamma and beta radiation the weighting factor is 1, so one gray equals one sievert — the assumption used in this converter.
