Name _____________________________________________________________ Date ___________ Per ___
Temperature Conversions, Dew Points & Relative Humidity
Solve for Fahrenheit or Celsius
Example:
What is 212 0F in 0C?
(212 – 32) = 180
180 x 5 = 900
900 / 9 = 100
Solution: 212 0F = 1000C
0
F = (90C) + 32
5
0
C = 5(F-32)
9
0
0
What is 20 C in F?
9 x 20 = 180
180 / 5 = 36
36+32 = 68
Solution: 20 0C = 68 0F
1. 68 0F = _____________
2. 80 0F = ______________
3. 40 0F = ______________
4. 37 0C = ______________
5. 90 0C = ______________
