1 MBq = 0.000027027027027027 Ci

1 Ci = 37,000 MBq

Example: 1000 MBq = 0.027027027027027 Ci

One megabecquerel is equal to 1,000,000 becquerels.

History: SI prefix mega- applied to the becquerel.

Current use: Common in medical imaging and radioactive source labeling.

Also written as MBq.

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.
