Wind Speed Unit/Force Converter implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

The converter has hazardous behavior at extreme finite inputs because ordinary JavaScript arithmetic overflows converted units to Infinity. Negative signed inputs also expose an unresolved speed-versus-direction convention and produce undefined Beaufort output unless explicitly rejected or converted to an absolute magnitude.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "wind_speed": 0,
    "unit": "m/s"
  },
  "expected_outputs": {
    "knots": 0,
    "mph": 0,
    "km/h": 0,
    "m/s": 0,
    "beaufort": 0
  },
  "working": "Start with 0 m/s. Knots: 0 / 0.514444 = 0 kt. mph: 0 x 2.236936 = 0 mph. km/h: 0 x 3.6 = 0 km/h. The speed is below 1 kt, so Beaufort = 0."
