How to Convert Rads to Grays
Converting rads (rad) to grays (Gy) is a common conversion in radiation dosimetry. One rad is equal to 0.01 grays.
Formula
Grays = Rads ÷ 100
or
Gy = rad ÷ 100
Step-by-step process
- Take the measurement in rads
- Divide that number by 100
- The result is the equivalent amount in grays
Examples
- 1 rad = 0.01 Gy
- 10 rad = 0.1 Gy
- 100 rad = 1 Gy
When to Convert Rads to Grays
This conversion is useful in radiation protection, medical imaging, and nuclear safety, where both rads and grays are used to quantify absorbed radiation dose.
Common Rads to Grays Conversions
Here is a table of common rad to gray conversions for quick reference:
| Rads (rad) | Grays (Gy) | Rads (rad) | Grays (Gy) |
|---|---|---|---|
| 1 | 0.01 | 100 | 1 |
| 10 | 0.1 | 200 | 2 |
| 50 | 0.5 | 500 | 5 |
| 100 | 1 | 1,000 | 10 |
Frequently Asked Questions
What is a Rad (rad)?
The rad (radiation absorbed dose) is a non-SI unit of absorbed dose, commonly used in the United States. One rad is equal to 0.01 gray.
What is a Gray (Gy)?
The gray (Gy) is the SI unit of absorbed dose, defined as the absorption of one joule of radiation energy per kilogram of matter.
