Pascal in MegaPascal, Umrechnung

Question

100 N/mm^2 = 100 MPa

Wieso gilt das bzw. Was mache ich falsch?

100 N/mm^2=100/1000000 N/m^2=1/10000 Pa=1*10^-10MPa

1Pa=1*10^-6 MPa

Comments

100/1000000 = 1/10000  = 1/10^4 = 1·10^{-4}

Answer 1

1 Pa = 1 N/m^2

1 m^2 = (1000 mm)^2 = 10^6 mm^2 

10^{-6} m^2 = 1 mm^2 

100 N/mm^{2} = (100 N) / (10^{-6} m^2) 

= (100 * 10^6 N)/(m^2) 

= 10^8 N/m^2 

= 100 * 10^6 N/m^2 

= 100 MPa 

Answer 2

Hallo,

$$ 1\frac{N}{mm^2}=1\frac{N}{(10^{-3}m)^2}=10^6\frac{N}{m^2}=10^6 Pa=1MPa\\$$

Answer 3

100 N/mm^2  ? 100 MPa

100 N/mm^2 * 1000 ^2 = 1 * 10 ^8 N / m^2

Mega ist 10 ^6

100 MPa
