Consumption formula for single needle lock stitch (plain/domestic) machine:
Where,
C = Thread consumption per inch,
N = Length of each stitch,
T = Thickness of fabric/seam,
S = Stitch density per inch.

So, C =?

C = (2N + 2T) × S
= 2NS + 2TS

So, C = 2 + 2TS; Because N × S = 1″

Problem:

If there are 10 stitches per inch and thickness is 0.025″, what will be threading Consumption per inch?

Solution: C= 2 + 2TS = 2 + 2 × 0.025″ × 10″ = 2.5″ (Ans.)
