What Is This Tool?

This converter transforms radiation absorbed dose measurements from millirad, a traditional unit used for low-level radiation doses, to centigray, a modern SI unit commonly applied in medical treatments and dosimetry.

How to Use This Tool?

  • Input the radiation dose value in millirad (mrd)
  • Select millirad as the source unit and centigray as the target unit
  • Execute the conversion to obtain the equivalent centigray measurement
  • Use the output for medical, safety, or environmental radiation dose applications

Key Features

  • Converts millirad (mrd) to centigray (cGy) using a defined conversion rate
  • Browser-based and straightforward to use
  • Supports users in translating legacy radiation doses into contemporary units
  • Helps standardize radiation dose documentation in clinical and environmental contexts

Examples

  • 100 millirad (mrd) equals 0.1 centigray (cGy)
  • 500 millirad (mrd) equals 0.5 centigray (cGy)

Common Use Cases

  • Reporting small diagnostic X-ray doses with legacy units translated into SI units
  • Monitoring environmental and occupational low-level radiation exposures
  • Calibrating survey meters and dosimeters that reference rad-based units
  • Planning and documenting radiation therapy doses using standardized units

Tips & Best Practices

  • Use conversions to compare historical and current radiation dose data accurately
  • Apply centigray units for documenting therapeutic radiation doses
  • Recognize the appropriate dose range for each unit—millirad for low doses, centigray for higher therapeutic levels
  • Verify calibration standards when interpreting converted values to avoid discrepancies

Limitations

  • Millirad is a legacy unit less common in modern practice, possibly causing varying calibration references
  • Centigray measures higher dose ranges, while millirad suits low or diagnostic doses
  • Conversions may involve rounding differences due to historical measurement standards

Frequently Asked Questions

What does millirad measure?
Millirad is a legacy CGS unit that quantifies absorbed radiation dose as one thousandth of a rad, representing low-level energy deposited by ionizing radiation.

Why convert millirad to centigray?
Converting millirad to centigray helps translate historical or low-dose radiation measurements into a modern SI unit commonly used in medical treatment and radiation safety.

What is the conversion rate from millirad to centigray?
1 millirad equals 0.001 centigray.

Key Terminology

Millirad (mrd)
A unit equal to one thousandth of a rad, used historically to measure low-level absorbed radiation doses.
Centigray (cGy)
A unit representing one hundredth of a gray, commonly used to quantify absorbed radiation doses in medical therapy.
Absorbed Dose
The amount of energy deposited by ionizing radiation per unit mass of material.
