How to Convert Millirads to Micrograys
To convert millirads to micrograys, multiply the absorbed radiation dose by the following conversion ratio: 10 micrograys/millirad.
Since one millirad is equal to 10 micrograys, you can use this simple formula to convert:
The absorbed radiation dose in micrograys is equal to the absorbed radiation dose in millirads multiplied by 10.
For example, here's how to convert 5 millirads to micrograys using the formula above.
How Many Micrograys Are in a Millirad?
There are 10 micrograys in a millirad, which is why we use this value in the formula above.
Our millirad to microgray calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millirads and micrograys are both units used to measure absorbed radiation dose. Keep reading to learn more about each unit.
What Is a Millirad?
A millirad is a unit of absorbed radiation dose equal to 1/100,000 of a gray (0.00001 Gy). One-thousandth of a rad (10 µGy). [1]
The millirad is classified as a standard unit of absorbed radiation dose. Millirads can be abbreviated as mrad; for example, 1 millirad can be written as 1 mrad.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millirad (mrad) a convenient decimal multiple of the gray (Gy).
In practice, millirads (mrad) are widely used across fine-tolerance laboratory, analytical, and micro-scale absorbed radiation dose measurements within international standard 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 millirads (mrad) and micrograys (µGy), keep full floating-point precision (1 mrad = 10 µGy; 1 µGy = 0.1 mrad) during intermediate calculations and round only the final microgray figure to match your instrument tolerance.
