Convert Thou (mil) to Inches

Thou (mil) → Inches
thou × 0.001 = in in × 1000 = thou

To convert thou (mil) (thou) to inches (in), multiply the thou (mil) value by 0.001. 1 thou = 0.001 in, and 1 in = 1000 thou. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert in to thou.

0.5 thou 0.0005 in
1 thou 0.001 in
2 thou 0.002 in
5 thou 0.005 in
10 thou 0.01 in
20 thou 0.02 in
50 thou 0.05 in
100 thou 0.1 in
500 thou 0.5 in
1000 thou 1 in
