One of the methods for determining the count of yarn is by making a lea of standard circumference and number of turns and finding its weight, from which the tex or the count of the yarn can be determined. The lea is usually made on a Wrap Reel, which may be either hand or motor operated. These leas may be also be used for the determination of the strength of yarn (Lea strength), or for conducting certain chemical or colour fastness tests. The leas may be either Imperial having a circumference of 54 inches and having 80 turns, or Metric having a circumference of one meter and having 100 turns.
