Estimate the extension rate (increase in length per time) of human hair in units of nanometers per second. You can start by approximating the growth rate of your hair in more familiar units by estimating how much you need to get trimmed off at a monthly haircut appointment? Answers within an-order of magnitude around the typical value will be accepted. a

4.899691358 nm/s

Explanation:

On average Human hair grows about 0.5 inch per month, every month, on average, men trim their hair 4 times. that is 0.125in/7.5 days.

Converting inches into nano meters and days into seconds gives us.

3175000nm/648000s = 4.899691358nm/s.
