Converting Textile Production in Kgs from Linear meter

Normally in Production in Textile Processing is recorded in linear meter. Sometimes the production in linear meters does not serve the purpose when it comes to specific energy consumption. For conversion of linear meter into kgs 3 parameters are required i) Linear Meters ii) Average Width iii) GSM

Production (kg) = 0.001 * Length (meter) * Width (meter) * GSM (gms / sq. meter)
