Question

Which of the following unit conversions is NOT correct?

• A. 1 Pascal = 1 N/m2
• B. 1 Mega Pascal = 1 N/mm2
• C. 1 Kilo Pascal = 10 N/mm2
• D. 1 Giga Pascal = 103 N/mm2

Answer 1

Answer:

C. 1 Kilo Pascal = 10 N/mm2

$1 pa = 1 N/m^2$

$1Mpa=10^6 pa =10^6N/m^2=1 N/mm^2$

$1Kpa=10^3pa =10^3N/m^2=10^{-3} N/mm^2$

$10^9pa=10^9N/m^2=10^3N/mm^2$
