Inputs are converted to canonical units before evaluating this stated formula. ## Rules - Empty optional inputs are undefined, not zero. - Hidden conditional inputs are ignored. - Do not invent missing required inputs. Notice: Illustrative defaults are not local quotes or verified legal rules. Dated reference components and user-entered assumptions are explicitly distinguished. Professional review is pending.
