Fahrenheit to Celsius
What this conversion does
Turn US-style Fahrenheit numbers into Celsius for international reports, science class, or metric-first appliances. Algebraically °C = (°F − 32) × 5/9. Body temperature, fry oil, and Chicago wind chill all use the same formula—the context changes the safe ranges, not the math.
When to use it
Medical cross-border records, importing US HVAC setpoints into EU energy models, or translating a Fahrenheit-only smoker chart for a Celsius probe. If you need absolute temperature next, continue through Celsius to Kelvin after this step.
