Convert Ergs per gram to Megarads
Convert Ergs per gram (erg/g) to Megarads (Mrad) instantly and accurately.
Conversion Formula
Mrad = erg/g × 1.000000000e-8
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 Megarads
The megarad (Mrad) equals 10⁶ rad = 10⁴ Gy. Used in radiation hardening of electronics and wire/cable insulation: cross-linked polyethylene (XLPE) cable insulation is cured at 5-20 Mrad; some legacy radiation hardness assurance (RHA) test reports for space electronics quote doses in Mrad(Si). 1 Mrad = 10⁴ Gy = 10 kGy.
