radtomGy

Convert rad (radiation absorbed dose) (rad) to milligrays (mGy).

Factor1 rad = 10 mGy

Converter

rad

Accepts numbers or expressions, e.g. 150 + 14.7

Result
10mGy

Rendered to 6 significant figures.

Formula

Formula
mGy = rad × 10

Multiply any value in rad (radiation absorbed dose) by 10 to obtain the value in milligrays.

Worked example

Convert 1 rad to mGy.

  1. 01Start with 1 rad.
  2. 02Multiply by the conversion factor: 1 × 10 = 10 mGy.
Result1 rad = 10 mGy

FAQ

What is the conversion factor from rad to mGy?
1 rad equals 10 mGy. To convert, multiply the value in rad (radiation absorbed dose) by 10.
How do I convert 1 rad to mGy?
1 rad = 10 mGy. For any value, multiply by 10.
How do I convert mGy back to rad?
Divide by the same factor — or equivalently, multiply by 0.1. So 1 mGy = 0.1 rad.
When would I need to convert rad (radiation absorbed dose) to milligray?
Radiation absorbed-dose conversions between rad and mGy are used in radiological protection, medical physics, and nuclear-industry health physics. Gray (Gy) is the SI standard; rad remains common in older US health-physics documentation (1 Gy = 100 rad).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
