Get an appropriate thermistor or similar thermosensor. Measure it under a range of known temperatures. Plot the curve. Put it into unknown temperature, take reading off the VOM, check the curve to see which temperature that reading is equivalent to. (Some higher-end VOMs come with a sensor which they are calibrated to read directly as degrees. )

.  What kind of accuracy do you need?
.  Do you want the VOM to read in degrees or can you convert from mV or ohms to degrees?
.  What temperature range are you measuring?
