    "Normal" atmospheric pressure is 101.325 kilopascals

    = 101,325 pascals

    = 101,325 newtons/meter².

    1 km² = (1,000 m) x (1,000 m) = 1 million m²

    Force = (101,325 N/m²) x (1 million m²)

    = 101,325,000,000 Newtons

    = 1.013 x 10¹¹ Newtons

    = 101.3 Giganewtons.

    That's the weight of all the air sitting on 1 km² of land.
