Reporting a calculation that looks wrong
The most useful reports include the numbers you entered, the result you got, and the value you expected (with a source if you have one). That lets us reproduce the case and fix the formula quickly.
What we cannot help with
BuildingsMath is a reference calculator, not design or engineering advice. We cannot size structural members, approve plans or certify a project β please consult a qualified professional or your local building authority for those decisions.
