I always wanted to know how thick paper really is, so here we go.
Step 1: Paper
I took 20 pieces of office paper.
Step 2: Measuring Paper
Measure all 20 pieces of paper at the same time. I used micrometer.
Step 3: Calculating Thickness
In my case one piece of paper is 0.0975 mm (0.00383858268 inches) thick.
