A wire cannot be measured by a straight scale, a thread must be used instead. To measure a curved line using a thread, follow the below steps:

  • Tie a knot at one end of the thread.
  • Place the thread at the beginning of the wire and try to measure a small initial portion of the wire which is relatively straight.
  • Place your thumb at the other end of the measured portion and measure next straighter portion.
  • Repeat the above step till the end of wire is reached. Make a knot at the end of the wire.
  • Now, straighten the thread and measure the length of the two knots on a scale.
