First, a cool (so to speak) on-line calculator that not only calculates the humidex from the temperature and relative humidity but also advises the appropriate response.

Next, a more sophisticated calculator in Microsoft Excel format. This accepts as inputs not only temperature and relative humidity, but also radiant contribution and atmospheric pressure. It produces as output the humidex, dew point, and five other wet bulb globe temperatures (WBGTs).
