How it works

  • This tool converts radioactivity (decay rate) units between one another. Enter a value and choose its unit, and the converted result for every unit is listed in a table.
  • The base unit is the becquerel (Bq), where 1 Bq represents one nuclear decay per second. Disintegrations per second (dps) is identical in value to the becquerel.
  • The curie (Ci) is a traditional unit; it is converted using the defined value 1 Ci = 3.7×10^10 Bq. The mCi and µCi use the same ratio.
  • kBq, MBq and GBq are decimal multiples formed with prefixes, corresponding to one thousand, one million and one billion becquerels respectively.
  • Extremely large or small values are shown in exponential notation; otherwise results are displayed with locale-aware digit grouping for readability.
  • This tool is for converting radioactivity (decay rate). Ambient dose rate (Sv/h) and exposure dose (Sv, Gy) are different physical quantities and cannot be converted here.
