°C → °F converter
For an absolute temperature, multiply Celsius by 9/5 and add 32. A change of 10 °C is instead a change of 18 °F: the 32-degree offset is not applied to differences. The converter has a separate Δ option for that purpose. Absolute values below −273.15 °C are rejected.
Conversion formula
°F = °C × (9/5) + (32)
