Hand formula: Applications & Measurement

The Hand formula, also known as the Hand rule, calculus of negligence, or BPL formula, is a conceptual formula created by United States Judge Learned Hand, which describes a process for determining whether a legal duty of care has been breached (constituting negligence). The original description of the calculus was in United States v. Carroll Towing Co.…
