Exercises
CONVERT
For this exercise F will be the symbol for the temperature in degrees Fahrenheit. C will be for the temperature in degrees Celsius. To convert from one scale to the other, you use one of the following formulas: (F – 32 ) × ($$\frac{5}{9}$$) = C and C × ($$\frac{9}{5}$$) + 32 = F

Question 1.
32° F = ____________ C
32° F = 0.95° C.

Explanation:
32° F = ?? C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
32° F = 32 ÷ 33.8
= 0.95° C.

Question 2.
100° C = ____________ F
100° C = 3,380° F.

Explanation:
100° C = ?? F.
Conversion:
1 Celsius = 33.8 Fahrenheit.
100° C = 33.8 × 100
= 3,380° F.

Question 3.
-149° F = ____________ C
-149° F = 4.41° C.

Explanation:
-149° F = ??  C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
-149° F = -149 ÷  33.8
= 4.41° C.

Question 4.
0° C = ____________ F
0° C = 0° F.

Explanation:
0° C = ____________ F
Conversion:
1 Celsius = 33.8 Fahrenheit.
0° C = 33.8 × 0
= 0° F.

Question 5.
100° F = ____________ C
100° F = 2.958° F.

Explanation:
100° F = ?? C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
100° F = 100 ÷ 33.8
= 2.958° F.

Question 6.
72° F = ____________ C
72° F = 2.130° C.

Explanation:
72° F = ?? C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
72° F = 72 ÷ 33.8
= 2.130° C.

Question 7.
32° C = ____________ F
32° C = 1081.6° F.

Explanation:
32° C = ?? F.
Conversion:
1 Celsius = 33.8 Fahrenheit.
32° C = 33.8 × 32
= 1081.6° F.

Question 8.
212° C = ____________ F
212° C = 7165.6° F.

Explanation:
212° C = ?? F.
Conversion:
1 Celsius = 33.8 Fahrenheit.
212° C = 33.8 × 212
= 7165.6° F.

Question 9.
40° F = ____________ C
40° F = 1.183° C.

Explanation:
40° F = ?? C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
40° F = 40 ÷ 33.8
= 1.183° C.

Question 10.
120° F = ____________ C
120° F = 3.550° C.

Explanation:
120° F = ?? C.
Conversion:
1 Celsius = 33.8 Fahrenheit.
120° F = 120 ÷ 33.8
= 3.550° C.

Question 11.
50° C = ____________ F
50° C = 1,690° F.

Explanation:
