Unit Converter (electrical) implementation

A source-bound implementation contract for Unit Converter (electrical); deployment and executable qualification remain separate.

Status: VERIFIED_CLEANLifecycle: implementation-contract

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.

Record owner: Guth Instruments
Lifecycle: verified-clean
Evidence ID: t4-006
Effect: Computation or source lookup only

Input and validation requirements

The extreme conversion 10^308 W to nW requires 10^317 nW, which overflows standard JavaScript Number arithmetic to Infinity. The converter should reject, flag overflow, or use arbitrary-precision handling.

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": {
    "value": 3.3,
    "from_unit": "kV",
    "to_unit": "V"
  },
  "expected_outputs": {
    "converted_value": 3300
  },
  "working": "kV factor = 1000; V factor = 1. converted_value = 3.3 × 1000 ÷ 1 = 3300 V."
}
