centigray to rad
Convert centigray (cGy) to rad (rad). Use an editable absorbed dose converter, conversion formula, and reference table.
1 cGy = 1 rad
Conversion formula
One centigray equals 1 rad. Multiply your value in centigray by this factor to get rad. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 centigray:5 × 1 = 5 rad

About these measurements
Absorbed dose measures energy deposited per unit mass.
The base reference used here is the gray. One centigray is 0.01 base units; one rad is 0.01 base units.
Important distinctions
Physical unit conversion only. Biological effect requires additional information and professional assessment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
