What does a 147mm line look like?

Answer 1

It's nearly impossible to describe length without getting you to pick up something around you (as screen sizes vary the sizes of lines that could be created through computer). If you have a 15cm ruler or even a 30cm ruler, look at 14 and 7/10 centimeter mark to 0. That's how long 147mm is. Otherwise, pick up a fullsize pencil. That's approx 14.7cm
