Answer 1

46,666,666.67 seconds (just convert it to hours for more comfortability)

Answer 2

Well, assuming you're bald, 18 months isn't very off. However, hair isn't constantly growing. Every two weeks, the hair cycle ceases and then restarts, so that for a certain short period of time hair doesn't grow at all. Regardless, I doubt you're bald. So, if you have short hair, about a year would be a good estimate, and if it's of mediocre length, maybe 9 months. Also, as you age, hair grows at a slower rate, except in the teenage years, of course. Much of it also depends on genetics; not all grow hair at the same rate. Also, curly hair grows faster than wavy hair, and wavy fastr than straight. There are too many variables to judge for sure.
