■ Example 2.34
Problem: Convert 33°C to °F.
Solution :
[(9/5) × 33°C] + 32 = 59.4 + 32 = 91.4°F
■ Example 2.35
Problem : Convert 81°C to °F.
Solution :
[(9/5) × 81°C] + 32 = 145.8 + 32 = 177.8°F
■ Example 2.36
Problem: Convert 65°C to °F.
Solution :
[(9/5) × 65°C] + 32 = 117 + 32 = 149°F
■ Example 2.37
Problem : Convert 63°F to °C.
Solution :
(5/9) × (63°F - 32) = (5/9) × 31 = 17.2°C
■ Example 2.38
Problem : Convert 67°F to °C.
Solution :
(5/9) × (67°F - 32) = (5/9) × 35 = 19.4°C
■ Example 2.39
Problem : Convert 57°C to °F.
Solution :
[(9/5) × 57°C] + 32 = 102.6 + 32 = 134.6°F
■ Example 2.40
Problem : Convert 28°F to °C.
Solution :
(5/9) × (28°F - 32) = (5/9) × -4 = -3.4°C
