What Is This Tool?
This converter helps translate absorbed radiation doses from kilogray, an SI-derived unit representing very high radiation levels, into millirad, a smaller legacy unit used primarily in medical and environmental dosimetry contexts.
How to Use This Tool?
-
Enter the dose value in kilogray (kGy) you want to convert
-
Select kilogray as the source unit and millirad as the target unit
-
Click the convert button to get the equivalent dose in millirads (mrd)
-
Review the result and use it for compatibility with legacy dosimetry data or equipment
Key Features
-

Tips & Best Practices
-
Ensure accurate input values for precise conversion
-
Use this tool to bridge SI and legacy radiation dose units for data compatibility
-
Consider the large numeric results when interpreting doses converted to millirads
-
Be mindful that millirad is a legacy unit less common in modern high-precision dosimetry
-
Verify the context of the dose magnitude before making comparisons between unit systems
Limitations
-
Millirad is a non-SI legacy unit and less frequently used in current scientific work
-
Converted values can be very large and challenging to interpret easily
-
Accuracy depends on the precision of the initial absorbed dose measurement
-
Differences in unit scales require careful consideration when comparing values
Frequently Asked Questions
-
What is the formula to convert kilogray to millirad?
-
Multiply the kilogray value by 100,000,000 to obtain the equivalent dose in millirads.
-
Why convert kilogray to millirad?
-
Conversion allows comparison with historical dosimetry data and compatibility with older equipment calibrated in rad-based units.
-
Is millirad still commonly used today?
-
Millirad is a legacy unit and less common in modern high-precision scientific measurements but remains useful in certain fields and for legacy data.
Key Terminology
-
Kilogray (kGy)
-
An SI-derived unit of radiation dose equal to 1,000 grays used to quantify high radiation absorption.
-
Millirad (mrd)
-
A legacy unit of absorbed radiation dose; one thousandth of a rad and equal to 1×10⁻⁵ gray.
-
Radiation Absorbed Dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
