A grid of spherically symmetric numerical models of the evolution of supernova remnants is calculated, covering the ambient density range n_0= 0.001 to 100 hydrogen atoms cm(-3) and with metallicities ranging from solar to primordial. These models are analyzed with the purpose of determining the relative mass fraction epsilon hot of hot gas (T>10(5) K) in the remnants as a function of time. From the work of Cioffi, McKee, and Bertschinger (1988), we derive an analytical formula for epsilon hot for times larger than the cooling time of the swept up gas shell and we demonstrate that all our model results are well fitted by this expression. Such an analytic expression is useful in models of a multi-phase interstellar medium, feedback mechanisms from supernovae in star-forming regions and in models of galaxy formation and evolution in general.
