Frequently asked questions
How many Microsieverts are in one Rad?
One Rad equals 10000 Microsieverts.
How do I convert Rad to Microsievert?
Multiply the number of Rads by 10000 to get Microsieverts. To go the other way, multiply Microsieverts by 1e-4 (or divide by 10000) to get Rads.
Is this conversion exact?
Yes. This conversion uses the exact defined relationship between Rad and Microsievert, so the result shown is mathematically precise (rounded only for display).

About this conversion
Rad and Microsievert are units used in the radiation family of measurements. Rad measures absorbed radiation dose (energy deposited per unit mass), while Microsievert measures equivalent radiation dose (biological risk-weighted dose). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Rad = 10000 Microsieverts (equivalently 1 Microsievert = 1e-4 Rads), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
