1 1/s = 0.000000000027027027027027 Ci

1 Ci = 37,000,000,000 1/s

Example: 1000 1/s = 0.000000027027027027027 Ci

Equivalent to one decay per second.

History: Mathematical reciprocal time unit.

Current use: Used in dimensional analysis and physics calculations.

Also written as 1/s.

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.
