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

1 nCi = 0.000000001 Ci

1 Ci = 1,000,000,000 nCi

Example: 1000 nCi = 0.000001 Ci

One nanocurie is equal to one billionth of a curie (1.0E-9 curies), or 37 becquerels.

History: Standard prefix applied to the curie.

Current use: Used for measuring very small radioactive concentrations.

Also written as nCi.

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.
