Convert Megarads to Millirads
Convert Megarads (Mrad) to Millirads (mrad) instantly and accurately.
Conversion Formula
mrad = Mrad × 1000000000
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.
About Millirads
The millirad (mrad) equals 10⁻³ rad = 10⁻⁵ Gy = 10 µGy. Older US health physics reports and NRC licence conditions quote occupational extremity doses in mrad; some film badge dosimetry reports still use mrad for historical continuity. 1 mrad = 10⁻³ rad = 10⁻⁵ Gy = 10 µGy.
