Let’s solve each problem step by step using the formula:
F = 1.8 × C + 32
We’ll plug in each Celsius temperature and calculate the Fahrenheit equivalent.
---
1) 25 °C
F = 1.8 × 25 + 32
= 45 + 32
=
77 °F
---
2) 6 °C
F = 1.8 × 6 + 32
= 10.8 + 32
=
42.8 °F
---
3) 10 °C
F = 1.8 × 10 + 32
= 18 + 32
=
50 °F
---
4) -40 °C
F = 1.8 × (-40) + 32
= -72 + 32
=
-40 °F *(Fun fact: This is where Celsius and Fahrenheit are equal!)*
---
5) -5 °C
F = 1.8 × (-5) + 32
= -9 + 32
=
23 °F
---
6) 103 °C
F = 1.8 × 103 + 32
= 185.4 + 32
=
217.4 °F
---
7) 30 °C
F = 1.8 × 30 + 32
= 54 + 32
=
86 °F
---
8) -12 °C
F = 1.8 × (-12) + 32
= -21.6 + 32
=
10.4 °F
---
9) 63 °C
F = 1.8 × 63 + 32
= 113.4 + 32
=
145.4 °F
---
10) 75 °C
F = 1.8 × 75 + 32
= 135 + 32
=
167 °F
---
11) -61 °C
F = 1.8 × (-61) + 32
= -109.8 + 32
=
-77.8 °F
---
12) 32 °C
F = 1.8 × 32 + 32
= 57.6 + 32
=
89.6 °F
---
13) -212 °C
F = 1.8 × (-212) + 32
= -381.6 + 32
=
-349.6 °F
---
14) 94 °C
F = 1.8 × 94 + 32
= 169.2 + 32
=
201.2 °F
---
15) Boiling point of water is 100 °C — what is it in Fahrenheit?
F = 1.8 × 100 + 32
= 180 + 32
=
212 °F
*(This is a key fact to remember: Water boils at 212°F!)*
---
Final Answer:
1) 77 °F
2) 42.8 °F
3) 50 °F
4) -40 °F
5) 23 °F
6) 217.4 °F
7) 86 °F
8) 10.4 °F
9) 145.4 °F
10) 167 °F
11) -77.8 °F
12) 89.6 °F
13) -349.6 °F
14) 201.2 °F
15) 212 °F
