4. Alec, a Cebu resident, will
go to New York for a
vacation.
He found out that the
weather in New York is
59°F.
What data should Zale first

5. °C = (°F – 32) / 1.8
°F = (°C x 1.8) + 32
K = C + 273.15
Conversion
Factors

6. 212 °F to °C
°C = (°F – 32) / 1.8
= (212– 32) / 1.8
= (180) / 1.8
= 100 °C
Celsius °C

7. 167 °F to °C
°C = (°F – 32) / 1.8
= (167– 32) / 1.8
= (135) / 1.8
= 75 °C
Celsius °C

8. 15 °C to °F
°F = (°C x 1.8) + 32
= (15 x 1.8) + 32
= (27) + 32
= 59 °F
Fahrenheit
°F

9. 52 °C to °F
°F = (°C x 1.8) + 32
= (52 x 1.8) + 32
= (93.6) + 32
= 125.6 °F
Fahrenheit
°F

10. 90 °C to °F
°F = (°C x 1.8) + 32
= (90 x 1.8) + 32
= (162) + 32
= 194 °F
Fahrenheit
°F

11. 100 °C to K
K = C + 273.15
= 100 + 273.15
= 373.15 K
Kelvin K

12. Alec, a Cebu resident, will
go to New York for a
vacation.
He found out that the
weather in New York is
59°F.
What data should Zale first

13. Should he bring a sweater?
Cebu = 29 °C
New York = 59 °F (covert to
°C) °C = (°F – 32) / 1.8
= (59 – 32) / 1.8
= (27) / 1.8
= 15 °C

14. 1.) 65 °F to °C
2.) 34 °F to °C
3.) 125 °C to °F
4.) 97 °C to K
5.) 54.22 °C to K
Convert the following
