Explanation

Use the exact affine transform: add 459.67 to Fahrenheit.

Method & Reference

Method basis: exact affine formula (scale + offset) shown in Snapshot.
Equation reference: °R = °F + 459.67
Consistency rule: forward and reverse pages use inverse equations to preserve scale reference points.

Reference note

This Fahrenheit to Rankine page uses explicit historical scale equations (scale + offset), not a simple multiplier.

Historical temperature scales are reconstructed from standard reference definitions.
Forward and reverse directions use inverse formulas, so each direction has its own dedicated page.
