- Start with your value in Gray. For example: 5 Gy
- Multiply by the conversion factor: 5 x 100
- The result is: 500 rad
Gray and Rad Relationship
This calculation facilitates standardized conversion between recognized units of radiation. Since 1 Gray equals approximately 100 Rads, the Gray represents a larger unit interval than the Rad. Understanding the relationship between Gray and Rad is essential for accurate calculations in physics, engineering, commerce, and daily applications.
About Gray
The gray (Gy) is the SI unit of absorbed radiation dose. It measures the amount of energy deposited in a mass of matter by ionizing radiation.
Common uses of Gray: medicine, nuclear physics, radiotherapy.
About Rad
The rad is a non-SI unit of absorbed radiation dose. One rad is equal to 0.01 gray.
Common uses of Rad: legacy radiation monitoring, industrial radiation.
