What's the gauge distance of the knitting machines

Knowing how to calculate the gauge distance helps you judge the production machine type, but don't forget to take into consideration the shrinkage from greige elastic to dyed elastic when it contains nylon yarn.

Basically in the market there are 15-gauge, 20-gauge, 24-gauge weft knitting machines and 18-gauge, 22-gauge, 28-gauge warp knitting machines. The gauge number means how many gauges are contained in one inch (25.4mm).

Take for example 20-gauge weft knitting machine, 25.4mm contains 20 gauge, 20 gauge contains 19 gauge distances, so each gauge distance is 25.4/(20-1)=1.34mm.

So, what's the gauge distance of the 15-gauge weft knitting machine?
