What does disintegrations per minute measure?

Disintegrations per minute (dpm) measure the number of nuclear decays occurring each minute, indicating the rate of radioactive disintegration.

Why use kilocurie [kCi] as a unit?

Kilocurie is used to express very large amounts of radioactive activity, often for industrial sources or regulatory calculations involving high activity.

Is this conversion suitable for low-level radioactivity?

No, because the conversion factor is extremely small, kilocurie units are not practical for low-level activities measured in dpm.
