Tensile or any other strength is simply maximum stress before the failure. It depends only on the maximum force and cross-section area. If you are using an initial cross-section area, such stress is called engineering stress. So, in your case, the tensile strength is simply 0.02 MPa or 0.204 kgf/cm². Note that a load can be measured in kgf (kilogram-force), not in kg (which is for mass).

Dear Sneha Paul,

in addition to what Evgenii Salganik said,

conversion of Pa (=N/m²) into kg/cm² is simply done by diving by g ( gravity acceleration of the earth; g=9,81m/s²).

Weight (=force) = mass*g; so weight w of a mass of 1 kg is equal to a force of:

w = 1kg*9,81m/s² = 9,81 N.

So just by dividing the 0,02MPa=0,02*106N/m² by g=9,81m/s² and figuring out the appropriate decimal powers as well as conversion of m² into cm² you will end up in kg/cm².

Thank you...Mr.Evgenii and Mr.Gerhard
