Quick Answer
°F = (°C × 9/5) + 32. °C = (°F - 32) × 5/9. K = °C + 273.15. The scales cross at -40° (where °C = °F). Water freezes at 0°C / 32°F / 273.15K and boils at 100°C / 212°F / 373.15K.
Design Notes
Electronics datasheets use Celsius exclusively. Standard operating ranges: commercial (0-70°C), industrial (-40 to 85°C), automotive (-40 to 125°C). Junction temperature is the most critical thermal parameter for IC reliability.
Common Mistakes
- 1
Forgetting the offset in Celsius-Fahrenheit conversion — it is NOT a simple multiplication.
- 2
Using ° symbol with Kelvin — correct notation is simply K, not °K.
- 3
Confusing temperature difference with absolute temperature — a 10°C rise = 18°F rise, but 10°C = 50°F.
Knowledge Base
Celsius para Fahrenheit?
°F = (°C × 9/5) + 32. Exemplo: 100°C = 212°F. Atalho: dobre e some 30.
Fahrenheit para Celsius?
°C = (°F - 32) × 5/9. Exemplo: 72°F = 22,2°C.
Quando F e C são iguais?
A -40°. O único ponto de cruzamento: -40°C = -40°F.
Que escala a eletrônica usa?
Celsius. Faixas: comercial (0–70°C), industrial (-40 a 85°C), automotivo (-40 a 125°C).
O que é 0 Kelvin?
Zero absoluto: -273,15°C. A temperatura mais baixa possível.
