How to measure a string without a Micrometer
How can I measure a string if I don’t have a micrometer?
Well, having a micrometer, a simple mechanical one, not a digital, is the most simple and trustable way to measure a string. But if you really can’t find one, here is a way to do it:
Take your string and turn as many spires as you can around your fingers, then put in a ruler and measure.
Then, divide for the number of spires.
...and... well... take out something, because probably you left some space in between the spires.
