Use this page to convert picocurie values into curie, with background details, formulas, a worked example, and a quick conversion table.

1 pCi = 0.000000000001 Ci

1 Ci = 1,000,000,000,000 pCi

Example: 1000 pCi = 0.000000001 Ci

One picocurie is equal to one trillionth of a curie (1.0E-12 curies), or 0.037 becquerels.

History: Standard prefix applied to the curie.

Current use: Common in US environmental health for measuring radon in air/water.

Also written as pCi.

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.
