    Stress to Force Calculator

    Calculate the force (kN) required given a stress (MPa) applied over a specific cross-sectional area.

    MPa
    Enter the material stress in Megapascals (1 MPa = 1 N/mm²)
    Enter the cross-sectional area perpendicular to the applied force
    Common Values
    -- kN

    Stress to Force Conversion Formula

    Force (N) = Stress (MPa) × Area (mm²)

    Since 1 MPa = 1 N/mm²

    To convert to kilonewtons (kN): Force (kN) = Force (N) ÷ 1000

    Area Unit Conversions

    • 1 m² = 1,000,000 mm²
    • 1 cm² = 100 mm²
    • 1 in² = 645.16 mm²
    • 1 ft² = 92,903 mm²

    Example: A stress of 650 MPa applied to 100 mm² area creates a force of 65 kN
