1 curie = 37000000000 becquerel

It was originally defined as "the quantity or mass of radium emanation in equilibrium with one gram of radium (element)", but is currently defined as 1 Ci = 3.7×1010 decays per second[4] after more accurate measurements of the activity of 226 Ra (which has a specific activity of 3.66×1010 Bq/g).
