Grammage & Basis Weight Conversions
Saturating Grade Papers

Grammage & Basis weight is the mass (weight) of paper for a given area. The decorative surfaces industry uses the following units of measure:

  • Grammage = grams per square meter (grams / m2 - square meter)
  • Basis Weight = pounds per 3,000 square feet (pounds / 3,000 ft2 - square feet)

Required input:

  • One of the following: Grammage, basis weight, square meters per kilo or square feet per pound

Key Features:

  • Converts between Grammage and basis weights and calculates the coverage per kilo and pound
  • Calculates the grammage and basis weights from the area that a pound or kilogram covers
  • Decimal point accuracy up to five places - default is 2 decimal places (1/100)


  • Step 1: Enter basis weight in (pounds or grams) or coverage in (square feet or square meters) in the appropriate field. Note: Grammage & basis weights are usually quoted on raw paper. On printed designs, pigments (ink) can add 3 to 10% to the basis weight depending on the design.
  • Press the 'PLANit' button.
  • The decimal places (located between the reset & 'PLANit' button) can be changed at any time. Note: The original value entered is not modified with the decimal change request.
  • To clear the values just press the reset button to clear or re-enter a new value.
