WebAnswer: The way I remember this personally is by recalling that room temperature amounts to a thermal energy of about kT\sim \frac{1}{40} \text{eV}. I rarely need a more precise figure, so then I just take T=300K as room temperature and multiply by 40 to get kT\sim 1 \text{eV} for a temperature ...
