Convert Microrads to Megarads
Convert Microrads (µrad) to Megarads (Mrad) instantly and accurately.
Conversion Formula
Mrad = µrad × 1.000000000e-12
About Microrads
The microrad (µrad) equals 10⁻⁶ rad = 10⁻⁸ Gy. Used in legacy US radiological instrumentation calibration documentation for very low-level survey instrument thresholds; some older NRC and EPA radiation protection records quote environmental dose rates in µrad/h when modern instruments report nGy/h. 1 µrad = 10⁻⁸ Gy = 10⁻² µGy.
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.
