Convert Kilorads to Microrads
Convert Kilorads (krad) to Microrads (µrad) instantly and accurately.
Conversion Formula
µrad = krad × 1000000000
About Kilorads
The kilorad (krad) equals 10 Gy. Used in radiation hardness testing of electronics for space and military applications: commercial components typically withstand 0.1-10 krad(Si); military-grade components are specified to 100-1000 krad(Si). Semiconductor device qualification standards (MIL-STD-883, ESCC 22900) quote total ionising dose in krad. 1 krad = 10 Gy.
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.
