Convert Kiloroentgens to Microroentgens
Convert Kiloroentgens (kR) to Microroentgens (µR) instantly and accurately.
Conversion Formula
µR = kR × 1000000000
About Kiloroentgens
The kiloroentgen (kR) equals 0.258 C/kg. Used in radiation hardness testing of electronics and legacy nuclear weapons effects literature; total ionising exposure inside nuclear facilities during design-basis accident scenarios is cited in kR; some older radiation therapy machine output specifications use kR/min. 1 kR = 0.258 C/kg = 10³ R.
About Microroentgens
The microroentgen (µR) equals 2.58 × 10⁻¹⁰ C/kg. Standard unit for very low environmental gamma dose rates in legacy US instrumentation: airborne radiological surveys over background areas report µR/h; EPA environmental monitoring network stations historically logged µR/h for outdoor gamma levels. 1 µR = 2.58 × 10⁻¹⁰ C/kg.
