Wind chill
is a non temperature that only life feels, but how is it calculated?

Wind chill is calculated using a formula that takes into account the air temperature (T) and wind speed (V), with the most commonly used formula being: Wind Chill (in Fahrenheit) = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16), where T is the air temperature in Fahrenheit and V is the wind speed in miles per hour; this formula is used by the National Weather Service and is only applicable for temperatures at or below 50°F and wind speeds above 3 mph.

Hm-mm?
How does one calculate a value of V^0.16? 
Is it V x (V x 0.16), or is it V x 0.16, or is it ... ... ...?

It means its the 1/.16th root of V.

Plug it into a calculator. If v=20,

20^.16 =~1.61497

I believe "^" means power, doesn't it Zorro?

And that's 0.16 power oF V, not 1/16 power which =0.0625.

You’re correct. But I said 1/.16 root. It’s the inverse of an exponent. So that, for example:

X^1/4 = the 4th root of x

Or V^.16 = the 1/.16 th root of V

Capiche?

🤔
How would one factor in the effect of wearing a wind breaker?

Mo Zero
That was my brother Jon (MoJo), not me (Mo One) who asked the last question in this forum.

As you are required to now know as a member of Gameknot: There are eight Mos in Gameknot.

Mo Zero: You
Mo One: Me
Mo Two: Shiva
Mo Three: Apatzer
Mo Nine: Stahl
Miss Mo: Brig
MoJo: Jon
Mo E=MC^2: Honorary

And I must have missed the "dot" (.) in your formula that indeed performs an inverse of the exponent.

Whatever

Twins are like the same person anyway.

humidity
On Saturday it was in the mid 20’s when I first stepped out, and on Sunday it was in the high thirty’s with the addition of higher humidly. They felt about the same, with Sunday perhaps feeling a bit nastier. Whats the formula for the effect of humidity on the “feels like” temp.

In Sacramento they were fond of reminding that, “yeah but it’s dry heat”, as in: not nearly so bad as high humidity at today's Sacto high of 95F. Later, living in swamp like Northern Va/ DC vicinity, the proof of that point was clearly demonstrated.
