The Codes do update/modify material values from time to time. So the answer depends on what Version of CAESAR II you're running and what Edition of the Code you are referring to.

I suggest you open a Support Request on Smart Support to obtain an answer.

Must be a matter of rounding. Caesar database is based on the Imperial units, the metric values in Caesar are the result of conversion so are very precise.

The metric values in B31.3 are rounded.

yes B31.3 rounding off the values in conversion of imperial to metric.

C-II done very accurately

Thank you once again Dan :-)
