Scope and limitations
Idealized classical model in SI units. Check sign conventions and assumptions; not a certified engineering design calculation.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
