Hello, new to this place. Started physics the other day in high school and already have homework. Not really good with conversion factors, so would like some help with a few of the problems i had 4 homework.(adsbygoogle = window.adsbygoogle || []).push({});

1.) Suppose your hair grows at the rate of 1/30 inch per day. Find the rate at which it grows. Because the distance between atoms in a molecule is on the order of 0.1 nm, your answer suggests how rapidly atoms are assembled in this protein synthesis.

I was thinking on changing inches to nanometers or whaterver NM means. Dont really know what 2 do after that.

2.)A rectangular building lot is 1.20*10^3 ft by 1.60*10^2 ft. Determine the area of this lot. Answer says its in m^2.

This is what i did so far. First one came out to 1200ft, and the other number comes out to 160ft. I know i multiply them to get the area, but how do i convert the answer to meters squared.
