## 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)
