What Is This Tool?

This online converter allows you to transform values from millirads, a historic radiation dose unit, to teragrays, an SI-derived unit for extremely large absorbed doses. It helps bridge old measurement systems with modern scientific scales.

How to Use This Tool?

  • Enter the dose magnitude in millirad (mrd) in the input field
  • Select millirad as the input unit and teragray as the output unit
  • Click the convert button to see the equivalent value in teragray (TGy)
  • Review example conversions to better understand the scale difference

Key Features

  • Converts radiation absorbed dose units between millirad and teragray
  • Supports comparison of very small and exceptionally large dose values
  • Browser-based tool requiring no installation
  • Provides sample conversions to illustrate unit relationships
  • Useful for theoretical and scientific dose scaling applications

Examples

  • 10 millirad equals 1×10⁻¹⁶ teragray
  • 100 millirad equals 1×10⁻¹⁵ teragray

Common Use Cases

  • Converting diagnostic X-ray doses from older rad-based units to modern SI units
  • Modeling energy deposition in extreme radiation environments like nuclear accidents
  • Supporting astrophysics and high-energy physics dose simulations
  • Cross-scale dose analysis for environmental and occupational monitoring
  • Calibrating instruments using legacy and contemporary unit systems

Tips & Best Practices

  • Understand the vast scale difference between millirad and teragray before conversion
  • Use conversions mainly for analytical or theoretical purposes due to scale extremes
  • Refer to provided examples to verify expected results
  • Check unit selections carefully to avoid confusion between small and large dose units

Limitations

  • Millirads measure very small radiation doses, while teragrays represent extraordinarily large absorbed doses
  • Due to the extreme scale difference, practical direct equivalence is uncommon
  • Conversion is mostly relevant in theoretical or cross-scale scientific contexts

Frequently Asked Questions

What is a millirad (mrd)?
A millirad is one thousandth of a rad, an older unit for measuring absorbed radiation dose, equal to 1×10⁻⁵ gray.

What does teragray (TGy) measure?
Teragray is an SI unit representing an extremely large absorbed radiation dose equal to 10¹² gray.

Why convert from millirad to teragray?
Converting helps express tiny legacy dose values as extremely small fractions of very large doses, useful in theoretical high-energy physics and radiation studies.

Key Terminology

Millirad (mrd)
A legacy CGS unit of absorbed radiation dose equal to one thousandth of a rad.
Teragray (TGy)
An SI-derived unit of absorbed radiation dose equal to 10¹² gray, used for extremely large dose measurements.
Gray (Gy)
The SI unit of absorbed radiation dose, defined as one joule of energy deposited per kilogram of matter.
