Basis Weight (GSM) ↔ ThicknessPulp & Mill

Convert sheet basis weight (GSM) to finished sheet caliper thickness (microns or mils) based on structural pulp densities.

Process Parameters
Projected Sheet Calliper
Thickness (Microns)168.0 μm
Thickness (Mils/Points)6.61 pt
Single Sheet Weight7.200g
Calculated based on a sheet size of 300 x 200 mm (Total Area: 0.0600 m²). Pulp physical compaction and pressing stages will reduce final thickness caliper by up to ~20%.
Pulp calculations align with standard TAPPI methods. Always run trial sheets to verify physical tear and tensile test strength results.
