Kelvin to Fahrenheit
From absolute scale to °F
Combine K → °C with °C → °F: first subtract 273.15, then apply °F = °C × 9/5 + 32. Handy when peer-reviewed plots sit in kelvin but your American HVAC subcontractor only tracks Fahrenheit delta-T rules.
When to use it
Interpreting infrared camera calibration tables, astronomy outreach (stellar temperatures are huge K numbers), or double-checking press releases. For °C-only workflows, stop at Kelvin to Celsius.
