Pls find below some
rules for calculate yarn length, count & weight.
Length (in yards) = Count *840 *weight
of yarn in pound
Count = Length / weight of
yarn in pounds*840
Weight of yarn = length/count *840

In this examples are related to filament. Note that
for filament we use direct system. In which most popular is denier. There are
other units too. For detail consult the tables at the end of the book. Denier
is number of grams per 9000 meters of filament.
For calculation related to denier we use following
equations:
Length of filament in meters = Weight of filament in grams* 9000
Denier
Weight of filament in grams = Length in meters * denier
9000
Denier = 9000*
Weight of filament in grams
Length of filament in
meters
Calculate
length of polyester filament from the given data:
Weight
690
grams
Denier
75
Equation:
Length of filament
in meters = Weight of filament in grams* 9000
Denier
= 690
* 9000
75
=82800 meters

Calculate weight of
polyester filament from the given data:
Length in meters = 50900
Denier
= 50
Equation: Weight of filament in grams
= Length in meters * denier
9000
= 50900*50
9000
=282.8 grams
