Converting from Roentgen (R) to Hectogray (hGy) in Radiation

What is Roentgen (R)

Roentgen (R) is a unit of measurement for ionizing radiation. It quantifies the amount of ionization in the air produced by X-rays or gamma rays.

What is Hectogray (hGy)

Hectogray (hGy) is a unit of absorbed dose of ionizing radiation. It measures the amount of energy deposited by radiation in a mass of tissue.
