Modulus of elasticity, problem. Graph and table.

[MMCS]

Attached is the graph and small part of table that i have chosen from the elastic range (first column extension, second column load) from a tensile test. I am trying to calculate youngs modulus of elasticity but can't seem to get a figure close to that of the common figure for the material

Material 0.1% carbon steel
Area = 20 x 10-6m²
Yield force = 6009N
Length increase at yield force = 0.537mm = 0.000537m
Original length = 50.mm = 0.05m


E = σ/ε

E = (6006/20x10-6) / (0.000537/0.05)
E = 27.96 x 10⁹
Typical value = 207 x 109

Iv obviously went very wrong somewhere but i don't know where

Thanks

For a start, send again but include the units at every step (as is good practice).

Are you certain that the original length of the wire was 50mm and not 50cm?
