About these units
The microsievert (µSv) is a metric unit of radiation dose, equal to 0.000001 sieverts.
The millisievert (mSv) is a metric unit of radiation dose, equal to 0.001 sieverts.
Going the other way, 1 millisievert = 1,000 microsieverts. 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.
