Temperature Conversions

2. Conversion Formulas F = (9 · C) + 32 5 C = K -273 C = 5 · ( F – 32 ) 9
F = Fahrenheit C = Celsius K = Kelvin

3. Practice Room Temp is 21 °C. What is room temperature in Kelvin?
K = C + 273
K =
K = 294

4. Practice
A medical thermometer registers a patient’s temperature to be 39° C. What is this in Fahrenheit?
F = (9 · C) + 32 5
F = (9 · 39) + 32
F = (351 ) + 32
F = (70) + 32
F = 102 °

5. Practice
A popsicle melts at 78 ° F. What is this temperature in Celsius?
C = 5 · ( F – 32 ) 9
C = 5 · ( 78 – 32 )
C = 5 · ( 46)
C = 230
C = or 26 °
