快速答案
25 °C = 77 °F
取整结果: 25 °C ≈ 77 °F
使用的公式
°F = (°C × 9/5) + 32
(25 × 9/5) + 32 = 77 °F
25 °C → 77 °F
日常含义

Celsius to Fahrenheit
°F = (°C × 9/5) + 32
Fahrenheit to Celsius
°C = (°F − 32) × 5/9
Celsius to Kelvin
K = °C + 273.15
Kelvin to Celsius
°C = K − 273.15
Fahrenheit to Kelvin
K = (°F − 32) × 5/9 + 273.15
Kelvin to Fahrenheit
°F = (K − 273.15) × 9/5 + 32
