Convert Microrads to Millirads
Convert Microrads (µrad) to Millirads (mrad) instantly and accurately.
Conversion Formula
mrad = µrad × 0.001
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 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.
