Square Meters: Multiply R-value by the insulation thickness. The resulting number is the square meter amount of insulation being used. For example, if you have 20 mm (20 millimeters = 0.2 m) of polyurethane foam insulation in your attic, with an R-value of 3.14, then multiply 0.2 x 3.14 = 0.6 square meter or 6 square feet of insulation
