How to convert kilograms per square meter second pascal to grams per square meter day kilopascal

This family uses vapor permeance, kg/(m²·s·Pa). The US perm factor is the conventional value at 0 °C, rounded per NIST. Material permeability requires thickness; perm-inch and porous-medium permeability in darcy or m² are excluded.

Use x for the value in kg/(m²·s·Pa), b for the intermediate value in kg/(m²·s·Pa), and y for the result in g/(m²·d·kPa).

g/(m²·d·kPa) = kg/(m²·s·Pa) ÷ 1.1574074074074074e-11

Worked examples

  • 10 kg/(m²·s·Pa) ≈ 864000000000 g/(m²·d·kPa)

    Step 1: (10 × 1) ≈ 10 kg/(m²·s·Pa).
    Step 2: 10 ÷ 1.15740740741e-11 ≈ 864000000000 g/(m²·d·kPa).

  • 20 kg/(m²·s·Pa) ≈ 1728000000000 g/(m²·d·kPa)

    Step 1: (20 × 1) ≈ 20 kg/(m²·s·Pa).
    Step 2: 20 ÷ 1.15740740741e-11 ≈ 1728000000000 g/(m²·d·kPa).

Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.

About Kilograms per square meter second pascal

Kilograms per square meter second pascal (kg/(m²·s·Pa)) measures permeability under the conventions above. The base value in kg/(m²·s·Pa) is (x × 1), where x is the numerical value in kg/(m²·s·Pa). Factors shown here are rounded for display; calculations use the stored factor.

About Grams per square meter day kilopascal

Grams per square meter day kilopascal (g/(m²·d·kPa)) measures permeability under the conventions above. The base value in kg/(m²·s·Pa) is (x × 1.15740740741e-11), where x is the numerical value in g/(m²·d·kPa). Factors shown here are rounded for display; calculations use the stored factor.
