Lamination and Converting Conversion Factors

Common Conversion Factors

When operating a laminator or other converting machinery, unit conversion is commonly required to complete a job.  For your convenience, we have compiled the most common conversion factors and listed them below.  You can use this guide to align your equipment operating conditions with material specs such as line speed, coating, weight, and bonding temperatures. 
 

• Line speed:
  • Meters Per Minute (MPM) = Feet Per Minute (FPM) X 0.3048
  • FPM = MPM X 3.281
• Thickness:
  • Mils = Micron X 0.0394
  • 1 Mil (25.4 microns) = 0.001 Inch
• Density:
  • GLI = grams/inch X 0.0057915 = N/15 mm
  • 1 GLI= 1 N/15 X 172.7
• Pressure:
  • Bar = Pounds per sq. inch (PSI ) X 0.06897
  • PSI = 1 Bar X 14.5
• Mass:
  • 1 Ream = 3000 sq. feet = 278.71 sq. meters
  • Grams per sq. meters (GSM) = Pound per ream X 1.628
  • Pound per ream (LB./R) = GSM X 0.6144
  • Mg/sq. meter = Mg/ream X 0.00359
• Weight:
  • Pound (LB) =4.45 Newtons (N)
  • 1 Newton = 0.225 pound
