How to Convert Centigrays to Micrograys
To convert centigrays to micrograys, multiply the absorbed radiation dose by the following conversion ratio: 10,000 micrograys/centigray.
Since one centigray is equal to 10,000 micrograys, you can use this simple formula to convert:
The absorbed radiation dose in micrograys is equal to the absorbed radiation dose in centigrays multiplied by 10,000.
For example, here's how to convert 5 centigrays to micrograys using the formula above.
How Many Micrograys Are in a Centigray?
There are 10,000 micrograys in a centigray, which is why we use this value in the formula above.
Our centigray to microgray calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Centigrays and micrograys are both units used to measure absorbed radiation dose. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Microgray?
A microgray is a unit of absorbed radiation dose equal to 1/1,000,000 of a gray (0.000001 Gy). Equal to 10⁻⁶ Gray. [2]
The microgray is classified as a metric and SI-compatible unit of absorbed radiation dose. Micrograys can be abbreviated as µGy; for example, 1 microgray can be written as 1 µGy.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microgray (µGy) a convenient decimal multiple of the gray (Gy).
In practice, micrograys (µGy) 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 centigrays (cGy) and micrograys (µGy), keep full floating-point precision (1 cGy = 10,000 µGy; 1 µGy = 0.0001 cGy) during intermediate calculations and round only the final microgray figure to match your instrument tolerance.
