About equivalent dose units

Convert sieverts, millisieverts, microsieverts, rem and millirem.

Dimensionally identical to absorbed dose, but weighted for biological effect — never mix grays and sieverts in the same calculation.

Dimensional formula: L² T⁻². Every conversion on this page goes through the sievert, using exact fractions rather than decimal approximations. Read how that works →
