nC/kg = C/kg × 1000000000
About Coulombs per kilogram
The coulomb per kilogram (C/kg) is the SI derived unit of radiation exposure, equal to 1 coulomb of ion charge liberated per kilogram of dry air. It replaced the roentgen in SI. Calibration of clinical X-ray beams with free-air ionisation chambers and parallel-plate chambers yields results in C/kg. 1 C/kg ≈ 3876 R.
About Nanocoulombs per kilogram
The nanocoulomb per kilogram (nC/kg) equals 10⁻⁹ C/kg. Used in modern SI-based environmental radiation monitoring; equivalent to ~3.88 µR. National metrology institutes calibrate secondary standard ionisation chambers with responses expressed in nC/kg. 1 nC/kg = 10⁻⁹ C/kg = 10⁻³ µC/kg.
