A quick units question. Serway gives the R value (for insulation) in English system units as:
\frac{ft^2 \, ^o F \, h}{BTU}

What unit does "h" represent? Thanks!

Alright, who moved it and why? I agree it's a "basic" question, but it is definitively NOT homework, which is why I put it in the General Physics category!

Hour. Long as there's a "pointer," who cares where it winds up --- let them fuss, and you get to be the adult --- you fuss and they fuss, and no one's an adult.

(Grumbles) It was too simple. (Sigh!) Thanks for telling me!

Oh, I agree. I just get a little excitable every now and then! :rolleyes:
