Apparel Weight Calculation or Fabric Consumption Calculation Formula:
To find out the apparel weight or fabric consumption, we should apply the following two formulas. By adding equation- (A) and equation (B), we will get the required fabric consumption for round neck t-shirt.

Fabric consumption calculation or apparel weight calculation,

     [{S.L + T.L + (2 × S.A) + (2× H.A)} × (1/2 Chest + S.A)] × G.S.M × 2
= ……………………………………………………………………......………        ….. (A)
                                                      10000

And,

Round neck collar fabric consumption calculation,

   {(Collar width + S.A) × (Neck round + S.A) × G.S.M × 2}
= …………………………………………....……………………             ……….. (B)
                                      10000

Here,
S.A means Seam allowance,
T.L means Total length,
H.A means Hem allowance, 
S.L means Sleeve length.


Apparel weight calculation for middle size i.e. L Size:


Let,
Hem allowance is 2cm,
Seam allowance is 2cm,

So,
From the equation- (A), we get,

     {24+62+ (2×2) + (2×2)} × (52+2)] ×160×2
= ………………………………………………………..
                               10000

     [{(24+62+4+4) × 54} × 160×2]
= ………………………………………….
                      10000

= 162.43 gms
= 0.162 kg

Again 
From the equation- (B), we get,

   {(3+2) × (54+2) ×160×2}
= ………………………………..
                 10000

     5×56×160×2
= ………………………
          10000

= 8.96 gms
= 0.09 kg

So,
Fabric consumption for one piece round neck T-shirt stands at,
= (0.162+0.09) kg
= 0.252 kg

And,
Fabric consumption for 10000 pcs round neck T-shirt is 
= Total order quantity × fabric consumption for one piece t-shirt
= 10000 pcs × 0.252 kg
= 2520 kgs.

So,
To calculate the above apparel export order, it needs 2520 kgs 100% cotton single jersey fabrics.
