Temperature conversion

In converting temperature from one scale to another, it is important to familiarize a few formulas in order to get the correct conversion.


In converting temperatures in Celsius scale into Fahrenheit scale, here are the steps:


Step #1: Multiply the temperature by 9

Step #2: Then divide by 5

Step #3: Then add by 32


The formula is

Celsius scale into Fahrenheit scale
Example 1
 212 °F
Explanation:

Step #1: Multiply the temperature by 9.

100 x 9 = 900


Step #2: Then divide by 5.

900 ÷ 5 = 180


Step #3: Then add by 32.

180 + 32 = 212

Therefore, 100°C = 212°F


In converting temperatures in Fahrenheit scale into Celsius scale, here are the steps:


Step #1: Subtract 32 from the temperature

Step #2: Then multiply by 5

Step #3: Then divide by 9


The formula is

Fahrenheit scale into Celsius scale
Example 2
 75°C
Explanation:

Step #1: Subtract 32 from the temperature.

167 – 32 = 135


Step #2: Then multiply by 5.

135 x 5 =675


Step #3: Then divide by 9.

675 ÷ 9 = 75

Therefore, 167°F = 75°C


In converting temperatures in Kelvin scale into Celsius scale, add the temperature by 273.


The formula is


Kelvin scale into Celsius scale
Example 3
 283°C
Explanation:

Step #1: Add the temperature by 273.

10 + 273 = 283


Therefore, 10 K = 283°C


In converting temperatures in Celsius scale into Kelvin scale, subtract the temperature by 273.


The formula is


Celsius scale into Kelvin scale
Example 4
 –223 K
Explanation:

Step #1: Subtract the temperature by 273.

50 – 273 = –223


Therefore, 50°C = –223 K


In converting temperatures in Fahrenheit scale into Kelvin scale, here are the steps:


Step #1: Convert into Celsius scale.

Step #2: Subtract by 273.


The formula is

Fahrenheit scale into Kelvin scale
Example 5
 –263 K
Explanation:

Step #1: Convert into Celsius scale.

50 – 32 = 48

18 x 5 = 90

90 ÷ 9 = 10


So,50°F = 10°C


Step #2: Subtract the temperature by 273.

10 – 273 = –263

Therefore, 50°F = –263 K


In converting temperatures in Kelvin scale into Fahrenheit scale, here are the steps:


Step #1: Convert into Celsius by adding 273.

Step #2: Convert into Fahrenheit scale.


The formula is

Kelvin scale into Fahrenheit scale
Example 6
 113°F
Explanation:

Step #1: Convert into Celsius by adding 273.

–228 + 273= 45

So, –228 K= 45°C


Step #2: Convert into Fahrenheit scale.

45 x 9 = 405

405 ÷ 5 = 81

81 + 32 = 113


Therefore, –228 K = 113°F
