How to Convert Milligrays to Micrograys
To convert milligrays to micrograys, multiply the absorbed radiation dose by the following conversion ratio: 1,000 micrograys/milligray.
Since one milligray is equal to 1,000 micrograys, you can use this simple formula to convert:
The absorbed radiation dose in micrograys is equal to the absorbed radiation dose in milligrays multiplied by 1,000.
For example, here's how to convert 5 milligrays to micrograys using the formula above.
How Many Micrograys Are in a Milligray?
There are 1,000 micrograys in a milligray, which is why we use this value in the formula above.
Our milligray to microgray calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Milligrays and micrograys 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 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 milligrays (mGy) and micrograys (µGy), keep full floating-point precision (1 mGy = 1,000 µGy; 1 µGy = 0.001 mGy) during intermediate calculations and round only the final microgray figure to match your instrument tolerance.
