Convert Rads to Micrograys (rad to µGy)
1 rad = 10000 micrograys (µGy). 1 µGy = 0.0001 rad. Example: 15 rad = 15 × 10000 = 150000 µGy.

How to Convert Rad to Microgray
- 1 rad = 10000 µGy
- 1 µGy = 0.0001 rad
- Example: convert 15 rad to µGy: 15 rad = 15 × 10000 µGy = 150000 µGy
Formula
µGy = rad × 10000
Derivation from SI units:
- 1 rad = 100 erg/g = 0.01 Gy.
- 1 µGy = 10⁻⁶ Gy.
- 1 rad = 0.01 Gy ÷ 0.000001 Gy per µGy = 10000 µGy
Both units are defined exactly, so the factor is exact. Rad definition: rad; Microgray definition: microgray.
Worked examples
- A reading of 0.5 rad converts to 5000 µGy.
0.5 rad × 10000 = 5000 µGy - A value of 5 rad is 50000 µGy.
5 rad × 10000 = 50000 µGy

Where it's used
Rads are used for US radiation safety and older literature, while micrograys appear in dental and chest X-ray air kerma. Both measure absorbed dose of ionising radiation, so the conversion is a fixed factor.

Frequently asked questions
How many micrograys are in 1 rad?
1 rad = 10000 µGy.
How do I convert rads to micrograys?
Multiply the value in rad by 10000. For example, 15 rad × 10000 = 150000 µGy.
Is the rad to µGy conversion exact?
Yes. Both units are defined exactly, and 1 rad is exactly 10000 µGy.
