How to Convert Milligrays to Centigrays
To convert milligrays to centigrays, multiply the absorbed radiation dose by the following conversion ratio: 0.1 centigrays/milligray.
Since one milligray is equal to 0.1 centigrays, you can use this simple formula to convert:
The absorbed radiation dose in centigrays is equal to the absorbed radiation dose in milligrays multiplied by 0.1.
For example, here's how to convert 5 milligrays to centigrays using the formula above.
How Many Centigrays Are in a Milligray?
There are 0.1 centigrays in a milligray, which is why we use this value in the formula above.
Our milligray to centigray calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Milligrays and centigrays are both units used to measure absorbed radiation dose. Keep reading to learn more about each unit.
What Is a Milligray?
A milligray is a unit of absorbed radiation dose equal to 1/1,000 of a gray (0.001 Gy). CT scan & diagnostic radiography absorbed dose unit (0.001 Gy). [1]
The milligray is classified as a metric and SI-compatible unit of absorbed radiation dose. Milligrays can be abbreviated as mGy; for example, 1 milligray can be written as 1 mGy.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milligray (mGy) a convenient decimal multiple of the gray (Gy).
In practice, milligrays (mGy) are widely used across fine-tolerance laboratory, analytical, and micro-scale absorbed radiation dose measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Centigray?
A centigray is a unit of absorbed radiation dose equal to 1/100 of a gray (0.01 Gy). Radiotherapy dose unit numerically equal to 1 rad (0.01 Gy). [2]
The centigray is classified as a metric and SI-compatible unit of absorbed radiation dose. Centigrays can be abbreviated as cGy; for example, 1 centigray can be written as 1 cGy.
In the metric system, "centi" is the standard SI prefix for hundredths, or 10⁻². This makes the centigray (cGy) a convenient decimal multiple of the gray (Gy).
In practice, centigrays (cGy) are widely used across fine-tolerance laboratory, analytical, and micro-scale absorbed radiation dose measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting absorbed radiation dose between milligrays (mGy) and centigrays (cGy), keep full floating-point precision (1 mGy = 0.1 cGy; 1 cGy = 10 mGy) during intermediate calculations and round only the final centigray figure to match your instrument tolerance.
