like if it's 80 outside and the humidity is 20% it feels like 87? like the wind chill factor with cold. but this is in hotness.

the wind chill temp empirical formula involved wind velocity and thermometer temp reading as shown by national weather services usa.
the heat stress temp empirical formula involved %humidity and thermometer temp reading as shown by environmental canada
the heat stress temp you quoted 87F is the temp felt by human which is not right because it will not be 87F if i have a fan blowing infront of me. i hope the university professor will change the heat stress temp empirical formula involving wind velocity. but as of now, heat stress temp involves only the relative humidity.

No, humidity is one of the factors considered in a "wind chill" factor. The wind chill factor is actually a "comfort" factor which takes wind, air dryness and actual temperature into account.
Humidity, on the other hand, is an absolute number. Rain is what happens when air exceeds 100% humidity. The 100% refers to the absolute number of lbs of moisture that atmospheric air can hold at saturation at a given temperature. For example, if air can hold 1 lb of moisture per cubic foot of air at a given temperature, then if at a given moment air contains 1/2 lb or moisture, the air is at 50% relative humidity.... 50% of its capacity. This number does not change... it's absolute and not subject to some "comfort" type of index anymore than a gallon jug can change it's capacity to hold water. A gallon jug will always hold a gallon of water.
Hope that helps.

It's called the Heat Index. High humidity causes the perception that the temperature is higher than it really is.

Actually, it does, but I don't know the formula off the top of my head. Relative humidity can make a difference in whether or not you feel colder or warmer. But like I said in all honesty, I don't know the formula.
Good Question!

It's called the heat index. It makes things miserable.

the dewpoint can alter how the air feels in temperature. higher dewpoint makes it more humid and feel hotter.
