What measure of units would you use to measure the thickness of a phone book
You would use millimetres.
Sheet metal thickness can be measured in mm. Sheet's thickness is very less.
Thickness of hair. However, most measurments at that level of precision would be made by scientists and they would use SI units, not pointless units like inches.
Units aren't used to measure anything. After you complete the measurement, using equipment suited to the purpose, you use units to describe the result of your measurement, and to tell other people about it. I would measure the thickness of a hair using a micrometer, and express the result in millimeters.

You would use millimetres.

thickness
Thickness is measured in units of length. You'd have to choose the one that gives a reasonable number corresponding to whatever you're measuring the thickness of. If it's the thickness of a hair, you'd probably select a sub-multiple of a meter. If it's the thickness of the atmosphere, you might select the kilometer. If it's the thickness of country gravy, that's a whole different story.

Millimetres, as in 1.5 mm. You could use a micrometer to measure thickness of a coin.
