Celcius to °F
F= 1.8°C multiply to the given of °C plus 32°
Example:
1.) 4°C to °F
°F = 1.8°C + 32°
= 1.8°(4°) + 32°
= 7.2° + 32°
= 39.2 °F
°F to °C
°C = (the given of °F subtract to 32° ) divided by 1.8
Example.
1.) 98.6°F to °C
°C = °F — 32° / 1.8°
= 98.6° —32° / 1.8°
= 66.7 ° / 1.8°
= 37°C
Hope you understand :)
