Whatever, I like my cigarette.

Tobacco tax is actually crazy. I can get 200 cigarettes for $10 CAD from the natives because it's tax free.

I heard from people. It is crazy, right?

I bet you’d use lightyears over petametres or exametres though.

It's more typical to use parsecs in practice for astronomy.

yeah, and imagine living without decameters and hectometers, unthinkable!

What's a "wet and windy" 0F? It's more or less a physical impossibility. 0F air can't hold much moisture. Also, it's not a killer.

Experience 0F wind in central North America or Central Asia vs 0F wind on the coast and tell me it’s not different. Also, it’s killer, not a killer, as in it sucks a lot.

There's still almost no moisture in the air at 0F, no matter if you're on the coast are in the middle of the continent. The air just can't hold that much water at that temp.

When it's warm:

   50% humidity @ 40C: 25.43 g/kg (grams of water / kg of air)
   90% humidity @ 40C: 45.78 g/kg
When it's cold:

   50% humidity @ -18C (~0F): 0.68 g/kg
   90% humidity @ -18C (~0F): 1.23 g/kg
There's just not enough there to cause any noticeable affect.

But you don't have to take my word for it, the US National Weather Service agrees:

"The results of the tests showed that relative humidity was an insignificant weather parameter, affecting the outcome to less than 1 degree"

You use the kit to test the harness of a finish coating, like a paint or a ceramic coating for cars. Pencils have their own hardness scale which can be used to gauge the hardness of the coating. Its really more of a relative qualitative test than quantitative as you'd use this for sample/coupon testing identical coatings. There are more absolute, quantitative methods to measure various hardness characteristics (scrat…

the pencil aspect is because its easy for a person to carry and take notes with? and you dont need to fit the car into a proper harness tester?

No, these are expensive pencils that have high quality assurance to make sure the graphite is as hard as it's supposed to be. You use a jig to hold the pencil in a specific way each time. Don't think of it as a pencil, it's a kit of rods made from graduated compositions of graphite and clay. You could write with one but that's like making a PB&J with the NIST peanut butter, a waste of money.
