What Is This Tool?

This converter allows you to translate radiation absorbed dose values measured in centigray (cGy) into millirad (mrd), a legacy unit. It helps bridge modern radiation dose measurements with older or rad-based systems used in various medical and environmental applications.

How to Use This Tool?

  • Enter the value in centigray (cGy) you want to convert
  • Select centigray as the source unit and millirad as the target unit
  • Click the convert button to see the equivalent dose in millirad (mrd)

Key Features

  • Converts centigray (cGy) to millirad (mrd) accurately based on defined unit relationships
  • Web-based and easy to use with quick results
  • Supports common radiation absorbed dose units used in medical physics and environmental monitoring

Examples

  • 5 cGy converts to 5000 mrd by multiplying 5 × 1000
  • 0.2 cGy converts to 200 mrd by multiplying 0.2 × 1000

Common Use Cases

  • Comparing modern radiotherapy doses with historical rad-based data
  • Environmental and occupational radiation exposure monitoring using legacy units
  • Calibrating and checking dosimeter readings that employ rad or millirad units

Tips & Best Practices

  • Ensure you understand that millirad is a legacy unit less common in current clinical practice
  • Use this converter to translate doses for comparison and compatibility with older equipment
  • Remember the conversion may not reflect measurement uncertainties or calibration differences

Limitations

  • Millirad is an older unit and not widely used in modern clinical settings
  • Conversions assume exact unit relationships and do not include measurement error factors
  • Small doses expressed in millirad might require very precise instruments to measure accurately

Frequently Asked Questions

What is the relationship between centigray and millirad?
1 centigray equals 1000 millirad, reflecting the conversion from a modern to a legacy radiation dose unit.

Why convert centigray to millirad?
Converting allows comparison of modern absorbed dose measurements with historical data or use on equipment calibrated with rad-based units.

Is millirad commonly used in clinical practice today?
Millirad is a legacy unit and is less commonly used in current clinical radiation therapy practices.

Key Terminology

Centigray (cGy)
A unit of absorbed ionizing radiation dose equal to one hundredth of a gray, used to quantify energy deposited by radiation per unit mass.
Millirad (mrd)
One thousandth of a rad, a legacy CGS unit of absorbed radiation dose equating to one ten-thousandth of a gray.
Absorbed Dose
The amount of radiation energy deposited in a material or tissue per unit mass.
