How to Convert Micrograys to Millirads

To convert micrograys to millirads, multiply the absorbed radiation dose by the following conversion ratio: 0.1 millirads/microgray.

Since one microgray is equal to 0.1 millirads, you can use this simple formula to convert:

millirads = micrograys × 0.1

The absorbed radiation dose in millirads is equal to the absorbed radiation dose in micrograys multiplied by 0.1.

For example, here's how to convert 5 micrograys to millirads using the formula above.

millirads = (5 µGy × 0.1) = 0.5 mrad

How Many Millirads Are in a Microgray?

There are 0.1 millirads in a microgray, which is why we use this value in the formula above.

1 µGy = 0.1 mrad|1 mrad = 10 µGy

Our microgray to millirad calculator automatically converts your absorbed radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Micrograys and millirads 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 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). [2]

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.

When converting absorbed radiation dose between micrograys (µGy) and millirads (mrad), keep full floating-point precision (1 µGy = 0.1 mrad; 1 mrad = 10 µGy) during intermediate calculations and round only the final millirad figure to match your instrument tolerance.
