2 N/cm2 = ? Pa
0,03 kPa = ? Pa
2,1 hPa = ? Pa
2 N/dm2 = ? kPa
3 N/cm2 = kPa

def: 1N/m² = 1 Pa
1cm = 10⁻²m
1cm² = 1cm * 1cm = 10⁻²m * 10⁻²m = 10⁻⁴m²

2N/cm² = 2N/10⁻⁴m² = 2 * 10⁴ N/m² = 2 * 10⁴ Pa = 20000 Pa

k = 10³
0,03 kPa = 0,03 * 10³ Pa = 30 Pa

h = 10²
2,1 hPa = 2,1 * 10² = 210 Pa

1dm = 10⁻¹m = 0,1m
1dm² = 1dm * 1dm = 10⁻¹m * 10⁻¹m = 10⁻²m² = 0,01 m²
2 N/dm² = 2N/10⁻²m² = 2*10² N/m² = 2*10² Pa = 2*10²*10⁻³ kPa = 0,2 kPa

3 N/cm² = 3 N/10⁻⁴m² = 3 * 10⁴ N/m² = 3 * 10⁴ Pa = 3 * 10⁴ * 10⁻³ kPa = 30 kPa
