1. The document discusses different temperature scales and how to convert between Celsius and Fahrenheit units. It introduces the Celsius scale developed by Anders Celsius in 1742 and the Fahrenheit scale developed earlier by Gabriel Fahrenheit. 2. Formulas are provided to convert between Celsius and Fahrenheit: Celsius = 5/9 (Fahrenheit - 32) and Fahrenheit = 9/5 Celsius + 32. 3. Examples are given applying the formulas to convert specific temperatures like 80°C to F° and 98.6°F to C°.

3. 1. recognize the different units for
temperature
2. convert one unit of temperature to another
unit

5. the degree of or of a
body or environment.
The two most common used temperature
scales are the and

6. The scale
was invented in the
early 1700s by
,
a German physicist.
Gabriel D. Fahrenheit

7. The scale was
develop in 1742 by
, a
Swedish astronomer.
Anders Celsius

8. Thermometer – a device used to measure temperature.

9. The following formulas will help us convert
from Fahrenheit to Celsius and vice versa.
Fahrenheit to Celsius
𝐶 =
5
9
(𝐹 − 32)
Celsius to Fahrenheit
𝐹 =
9
5
𝐶 + 32

10. Take note of that:
0° 𝐶 = 32° 𝐹
100°𝐶 = 212° 𝐹

12. 𝐹 =
9
5
𝐶° + 32
Example 1:
Convert each to
the indicated unit.
a. 80° 𝐶 𝑡𝑜 𝐹°
=
9
5
(80) + 32
= 144 + 32
𝐹 = 176∴ 80℃ = 176℉

13. 𝐹 =
9
5
𝐶° + 32
Example 2:
Convert each to
the indicated unit.
a. 20° 𝐶 𝑡𝑜 𝐹°
=
9
5
(20) + 32
= 36 + 32
𝐹 = 68∴ 20℃ = 68℉

14. 𝐶 =
5
9
(𝐹 − 32)
Example 3:
Convert each to
the indicated unit.
a. 98.6° 𝐹 𝑡𝑜 𝐶°
=
5
9
(98.6 − 32)
=
5
9
(66.6)
𝐶 = 37∴ 98.6℉ = 37℃
