Which of the following conversion formula is correct for temperature units 

Explanation:

Celsius scale 

• In this scale, LFP (ice point) is taken 0° and UFP (steam point) is taken 100°.
• The temperature measured on this scale all in degree Celsius (° C).

Fahrenheit scale 

• This scale of temperature has LFP as 32° F and UFP as 212° F .
• The change in temperature of 1° F corresponds to a change of less than 1° on the Celsius scale.

Kelvin scale 

• The Kelvin temperature scale is also known as the thermodynamic scale. The triple point of water is also selected to be the zero of the scale of temperature.
• The temperatures measured on this scale are in Kelvin (K).

Rankine scale

• This scale of temperature has LPF as 492° R and UFP as 672° R.
• Interval of this scale is according to Fahrenheit.
• The temperature measured on this scale are in Rankine (R)

All these temperatures are related to each other by the following relationship

\(\frac C{100}= \frac {F-32}{180}=\frac {R-492}{180}= \frac {K -273}{100}\)

Additional Information

Relationship between the Celsius and Fahrenheit scale is –

\(\frac{F-32}{9}=\frac{C}{5}\)

\(\Rightarrow C=\frac{5}{9}\left( F-32 \right)\)
