What Is This Tool?
This converter transforms values from centigray per second (cGy/s), a unit measuring radiation absorbed dose rate, into watt per kilogram (W/kg), the SI derived unit used for power absorbed or emitted per unit mass. It helps express radiation dose rates in terms of energy deposition per mass and is widely relevant in medical and engineering contexts.
How to Use This Tool?
-
Enter the numerical value in centigray per second (cGy/s) into the input field
-
Select centigray/second as the source unit and watt/kilogram as the target unit
-

Examples
-
Converting 5 cGy/s: 5 × 0.01 = 0.05 W/kg
-
Converting 20 cGy/s: 20 × 0.01 = 0.20 W/kg
Common Use Cases
-
Measuring beam delivery rates in external-beam radiotherapy and linear accelerator output
-
Calibrating dosimeters and radiation sources for medical physics and radiobiology experiments
-
Expressing Specific Absorption Rate (SAR) for electromagnetic exposures in safety standards
-
Assessing power density per mass in engineering materials such as reactor fuel
Tips & Best Practices
-
Always verify unit selections to ensure correct conversion direction
-
Consider calibration standards and context since biological effects depend on more than energy rate alone
-
Use this conversion for preliminary estimations and supplement with detailed dosimetry data when needed
-
Regularly update your knowledge of radiation safety limits relevant to your application
Limitations
-
Conversion is based on a direct equivalence of energy deposition rate without accounting for radiation type or tissue characteristics
-
Does not reflect biological effects, which require additional factors beyond pure dose rate
-
Accurate interpretation requires specific calibration and consideration of the radiation context
Frequently Asked Questions
-
What does centigray per second measure?
-
Centigray per second quantifies the absorbed radiation dose rate, indicating how much radiation energy is deposited in a material per second.
-
Why convert cGy/s to W/kg?
-
Converting to watt per kilogram expresses the radiation dose rate in terms of power absorbed per unit mass, a standard measure useful in dosimetry and safety assessments.
-
Are the biological effects fully described by this conversion?
-
No, biological effects depend on factors such as radiation type and tissue properties; this conversion represents only the energy deposition rate.
Key Terminology
-
Centigray per second [cGy/s]
-
A unit representing the absorbed radiation dose rate equal to 0.01 gray per second, showing how fast radiation energy is deposited.
-
Watt per kilogram [W/kg]
-
The SI derived unit of power absorbed per unit mass, numerically equivalent to dose rate in grays per second for radiation energy deposition.
-
Specific Absorption Rate (SAR)
-
A measure of electromagnetic energy absorbed per unit mass of biological tissue, used to assess exposure safety.
