For the Arrhenius-Weibull relationship, the reliable life,  <math>{{t}_{R}}</math> , of a unit for a specified reliability and starting the mission at age zero is given by:
 
<br>
::<math>{{t}_{R}}=C\cdot {{e}^{\tfrac{B}{V}}}{{\left\{ -\ln \left[ R\left( {{t}_{R}},V \right) \right] \right\}}^{\tfrac{1}{\beta }}}</math>
 
<br>
This is the life for which the unit will function successfully with a reliability of  <math>R({{t}_{R}})</math> . If  <math>R({{t}_{R}})=0.50</math>  then  <math>{\breve{T}</math>,
the median life, or the life by which half of the units will survive.
