Convert Ergs per gram to Milligrays
Convert Ergs per gram (erg/g) to Milligrays (mGy) instantly and accurately.
Conversion Formula
mGy = erg/g × 0.1
About Ergs per gram
The erg per gram (erg/g) equals exactly 10⁻⁴ Gy and is the CGS-Gaussian unit of absorbed dose. Because 1 rad was originally defined as 100 erg/g, this unit is directly linked to the historical radiation system. Still found in older nuclear physics and health physics texts predating SI adoption. 1 erg/g = 10⁻⁴ Gy = 0.1 mGy.
About Milligrays
The milligray (mGy) equals 10⁻³ Gy and is the standard unit for diagnostic radiology patient doses. CT head scan ~20-60 mGy; abdominal CT ~10-30 mGy; mammography mean glandular dose ~1-3 mGy. IAEA and EU medical exposure directives set diagnostic reference levels in mGy. 1 mGy = 10⁻³ Gy = 0.1 rad.
