TEMPERATURES

TEMPERATURES 59°F = (59-32) × 5/9 = 15°C

20°C = (20 × 9/5) + 32 = 68°F

A rough-and-ready way of converting centigrade Fahrenheit and vice versa: start from the fact that

to

Une manière rapide de convertir les centigrades Fahrenheit et vice versa : en prenant pour base

en

10°C = 50°F Thereafter for every 5°C add 9°F

5°C équivalent à 9°F

Thus:

Ainsi : 15°C = (10 + 5) = (50 + 9) = 59°F 68°F = (50 + 9 + 9) = (10 + 5 + 5) = 20°C
