Converting from Centigray (cGy) to Roentgen (R) | Radiation

What is Centigray (cGy)

Centigray (cGy) is a unit of measurement used in the field of radiation to quantify the amount of ionizing radiation absorbed by a specific material. It is equal to one hundredth of a gray (1 cGy = 0.01 Gy).

What is Roentgen (R)

Roentgen (R) is another unit of measurement for ionizing radiation exposure. It measures the amount of radiation required to produce a specific amount of ionization in air. One Roentgen is defined as the exposure to X-rays or gamma rays that produces 2.58 × 10^(-4) coulombs per kilogram of air.

Conversion Formulas

The default conversion between Centigray (cGy) and Roentgen (R) is as follows:

• 1 cGy=1.15 R

• 1 R=0.8695652 cGy

Examples

Here are some common conversions between Centigray (cGy) and Roentgen (R):

• 10 cGy = 11.5 R
• 12 cGy = 13.8 R
• 15 cGy = 17.25 R
• 10 R = 8.695652 cGy
• 12 R = 10.43478 cGy
• 15 R = 13.04348 cGy

Use these conversion values as a reference when working with radiation measurements in the cGy and R units.
