How to Convert Micrograys to Milligrays
To convert micrograys to milligrays, multiply the absorbed radiation dose by the following conversion ratio: 0.001 milligrays/microgray.
Since one microgray is equal to 0.001 milligrays, you can use this simple formula to convert:
The absorbed radiation dose in milligrays is equal to the absorbed radiation dose in micrograys multiplied by 0.001.
For example, here's how to convert 5 micrograys to milligrays using the formula above.
How Many Milligrays Are in a Microgray?
There are 0.001 milligrays in a microgray, which is why we use this value in the formula above.
Our microgray to milligray calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Micrograys and milligrays are both units used to measure absorbed radiation dose. Keep reading to learn more about each unit.
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. [1]
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.
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). [2]
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.
When converting absorbed radiation dose between micrograys (µGy) and milligrays (mGy), keep full floating-point precision (1 µGy = 0.001 mGy; 1 mGy = 1,000 µGy) during intermediate calculations and round only the final milligray figure to match your instrument tolerance.
