Enter the number of knots along the warp and weft, and the length of the warp and weft used for counting to determine the knots per square inch.

Knots Per Square Inch Formula

The following equation is used to calculate the Knots Per Square Inch.

KPSI = (KWarp * KWeft) / (LWarp*LWeft)

  • Where KPSI is the knots per square inch
  • KWarp is the number of knots along the warp
  • Kweft is the number of knots long the weft
  • LWarp is the length of the warp (inches)
  • Lweft is the length of the weft (inches)
