    Temperature and 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
    4 177 ° C 350 ° F Moderate
    5 190 ° C 375 ° F Moderate
    6 200 ° C 400 ° F Moderately Hot
    7 220 ° C 425 ° F Hot
    8 230 ° C 450 ° F Hot
    9 245 ° C 475 ° F Hot
    10 260 ° C 500 ° F Extremely Hot
    Simple conversion formula: to convert Celsius to Fahrenheit minus 2, times 2, plus 32.
