Convert Micrograys to Rads (µGy to rad)
1 microgray (µGy) = 0.0001 rads (rad). 1 rad = 10000 µGy. Example: 15 µGy = 15 × 0.0001 = 0.0015 rad.

How to Convert Microgray to Rad
- 1 µGy = 0.0001 rad
- 1 rad = 10000 µGy
- Example: convert 15 µGy to rad: 15 µGy = 15 × 0.0001 rad = 0.0015 rad
Formula
rad = µGy ÷ 10000
Derivation from SI units:
- 1 µGy = 10⁻⁶ Gy.
- 1 rad = 100 erg/g = 0.01 Gy.
- 1 µGy = 0.000001 Gy ÷ 0.01 Gy per rad = 0.0001 rad
Both units are defined exactly, so the factor is exact. Microgray definition: microgray; Rad definition: rad.
Worked examples
- A reading of 0.5 µGy converts to 0.00005 rad.
0.5 µGy × 0.0001 = 0.00005 rad - A value of 5 µGy is 0.0005 rad.
5 µGy × 0.0001 = 0.0005 rad

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

Frequently asked questions
How many rads are in 1 microgray?
1 µGy = 0.0001 rad.
How do I convert micrograys to rads?
Multiply the value in µGy by 0.0001, or divide it by 10000. For example, 15 µGy × 0.0001 = 0.0015 rad.
Is the µGy to rad conversion exact?
Yes. Both units are defined exactly, and 1 µGy is exactly 0.0001 rad.
