Temperature & Energy Conversion

Temperature
Convert Fahrenheit to Celsius (degrees F - 32) x 0.555 degrees C
Convert Celsius to Fahrenheit (degrees C x 1.8) + 32 degrees F
Water Boils at 212° F 100° C
Normal body temperature 98.6° F 37° C
Water Freezes at 32° F 0° C
Room temperature 68° F 20° C
Air Temperatures: degrees Celsius (C) to degrees Fahrenheit (F)
0° C = 32° F 5° C = 41° F 10° C = 50° F 15° C = 59° F
20° C = 68° F 25° C = 77° F 30° C = 86° F 35° C = 95° F
Oven Temperatures
Gas Mark Celsius (C) Fahrenheit (F) Description
1/2 130 ° C 250 ° F Very Slow
1 140 ° C 275 ° F Very Slow
2 150 ° C 300 ° F Slow
3 170 ° C 325 ° F Slow
