# Kc ⇄ Kp Converter implementation

A source-bound implementation contract for Kc ⇄ Kp Converter; deployment and executable qualification remain separate.

Status: **VERIFIED_CLEAN**Lifecycle: **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**: t4-111

**Effect**: Computation or source lookup only

## Input and validation requirements

An unvalidated input of T = 0 K with Δn = -1 produces 0^-1, an undefined division by zero. Temperature-unit ambiguity can also produce an incorrect result if a Celsius value is accepted as Kelvin.

## 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.
