To measure for cutting or checking the length

To measure for cutting or checking the length
Measuring a rope without a rope measurer is a tricky operation, because the result is never
very precise.
However it is advised to double the rope and then double again, so that only 1/4 of the length
then has to be actually measured with your tape.
Then multiply by 4 to obtain a reasonably accurate length for the rope.
Example: You wish to check that your rope is actually 60m.
Double it, then double one of the halves again and measure it.
It represents around 1/4 of the rope.
If your rope is 60m the part measured will be 15m long.
If you wish to obtain two ropes of the same length:
In this case there is no need to use a tape.
Just double the rope and cut it.
