1 kBq = 0.000000027027027027027 Ci

1 Ci = 37,000,000 kBq

Example: 1000 kBq = 0.000027027027027027 Ci

One kilobecquerel is equal to 1,000 becquerels.

History: SI prefix kilo- applied to the becquerel.

Current use: Used for lower-level radioactive sources and contamination limits.

Also written as kBq.

One curie is approximately the activity of 1 gram of the radium isotope 226Ra, equal to 3.7E+10 becquerels.

History: Named after Pierre and Marie Curie. Originally defined in 1910.

Current use: Still commonly used in the United States and in some clinical settings alongside the becquerel.

Also written as Ci, curies.
