Radiation Absorbed Dose (Gray) converter
Convert mGy to µGy — milligray to microgray
Convert milligrays (mGy) to micrograys (µGy) instantly. 1 mGy = 1,000 µGy. Free calculator with formula, conversion table, and Gy base-unit equivalent.
Quick mGy to µGy answer
1 mGy = 1,000 µGy
multiply by 1,000
10 mGy = 10,000 µGy
milligray to microgray formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mGy to µGy conversion uses the exact factor 1,000.
µGy = mGy × 1,000
10 mGy × 1,000 = 10,000 µGymGy to µGy table

Understanding milligrays and micrograys
When dealing with radiation absorbed dose (gray), accuracy is paramount. The difference between a milligray (mGy) and a microgray (µGy) might seem small, but it represents a magnitude difference of one thousand. In scientific notation, a milligray is expressed as 10⁻³, while a microgray is 10⁻⁶ of the base unit (gray).
Converting from milligrays to micrograys is a standard mathematical operation across various technical fields, as they are commonly used in radiation therapy dosing, diagnostic radiology (fluoroscopy, CT scans), and radiobiology. The conversion is always an exact multiple of 1,000, meaning you simply move the decimal point three places to the right (when converting milli to micro) or three places to the left (when converting micro to milli).
Because the metric system is based on powers of ten, learning how to quickly translate mGy into µGy (or vice-versa) can save valuable time in laboratory environments, engineering calculations, and academic research. We designed this mGy to µGy calculator to perform this exact transformation without any floating-point errors, ensuring that whether you are working with 10 mGy or much larger figures, your final microgray value is perfectly precise.
When to use mGy vs µGy
milligrays and micrograys are used in radiation therapy dosing, diagnostic radiology (fluoroscopy, CT scans), and radiobiology. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
