What Is This Tool?

This unit converter helps transform values of absorbed radiation dose from millirad (mrd), a legacy unit, into kilogray (kGy), an SI-derived unit for much higher doses. It is designed for professionals and enthusiasts working with radiation measurements across medical, environmental, and industrial fields.

How to Use This Tool?

  • Enter the absorbed dose value in millirad (mrd)
  • Select millirad as the input unit and kilogray as the output unit
  • Click the convert button to see the equivalent dose in kilogray
  • Review the results and refer to unit definitions for clarity

Key Features

  • Converts radiation dose from millirad (mrd) to kilogray (kGy) instantly
  • Browser-based and easy to use with no installation required
  • Supports dose comparison between low-level and high-dose radiation units
  • Provides clear unit definitions and practical use cases
  • Suitable for medical, environmental, and industrial radiation contexts

Examples

  • 1,000 millirad equals 0.00001 kilogray
  • 500,000 millirad equals 0.005 kilogray

Common Use Cases

  • Comparing small diagnostic X-ray doses with high industrial radiation doses
  • Relating historical rad-based measurements to modern SI units
  • Calibrating dosimeters and survey meters using legacy units
  • Applying radiation dosimetry data in sterilization and materials processing
  • Performing environmental and occupational dose monitoring at low exposure levels

Tips & Best Practices

  • Ensure unit consistency when interpreting converted values
  • Use this tool to bridge legacy and modern radiation dose units accurately
  • Understand the scale difference between millirad and kilogray for proper application
  • Check context carefully, especially when dealing with very small or very large doses

Limitations

  • Millirad is a non-SI legacy unit that may not be commonly used today
  • Conversions produce very small numbers due to the large difference in dose magnitude
  • Practical applications may be limited when comparing low doses to high-dose contexts
  • Precision is important because of the tiny numeric values arising from conversion

Frequently Asked Questions

What does one millirad represent in gray units?
One millirad equals one ten-millionth of a kilogray, which is 1×10⁻⁵ gray.

For what applications is the kilogray unit commonly used?
Kilogray is used in industrial sterilization, food irradiation, and polymer material processing involving very high radiation doses.

Why is converting millirad to kilogray challenging?
Because millirad measures very small doses and kilogray very large doses, conversions yield extremely small numbers requiring careful interpretation.

Key Terminology

Millirad (mrd)
A thousandth of a rad; a legacy absorbed dose unit quantifying small radiation energy deposits per mass.
Kilogray (kGy)
An SI-derived absorbed dose unit equal to 1,000 grays, used for expressing very high radiation doses.
Absorbed Dose
The energy deposited by ionizing radiation in a unit mass of material, measured in units like rad, gray, and their derivatives.
