coulomb/kilogram to
roentgen

roentgen to
coulomb/kilogram

Unit Definitions:

coulomb / kilogram

C/kg

Contextual Explanation

The standard SI derived unit of ionizing radiation exposure. It represents the amount of X-ray or gamma radiation required to create 1 Coulomb of electrical charge of either sign within 1 kilogram of dry air at standard conditions.

Practical Applications

Primary standard for radiation exposure measurements, calibration of air ionization chambers, and fundamental reference physics for beam outputs.

roentgen

R

Contextual Explanation

A traditional non-SI unit of radiation exposure. Originally defined as the quantity of X or gamma radiation that produces 1 electrostatic unit (esu) of charge per cubic centimeter of dry air at STP.

Practical Applications

Historical medical radiology records, legacy US radiation safety regulations (still occasionally seen in survey meters measuring mR/h), and historical dosimetry.

Example Calculation

To convert 1 coulomb/kilogram [C/kg] to roentgen [R]:
