## Relation between different temperature scales

1. $\dpi{100}&space;\mathbf{\frac{C&space;-&space;0}{100}&space;=&space;\frac{F&space;-&space;32}{180}&space;=&space;\frac{K&space;-&space;273}{100}}$
2. $\dpi{100}&space;\mathbf{\frac{C&space;-&space;0}{100}&space;=&space;\frac{F&space;-&space;32}{180}&space;}$
3. $\dpi{100}&space;\mathbf{\mathbf{\frac{x&space;}{5}&space;=&space;\frac{x&space;-&space;32}{9}&space;}}$
4. cross multiply and solve for x
5. $\dpi{100}&space;\mathbf{9x&space;=&space;5x&space;-&space;160}$
6. 9x – 5x = – 160
7. 4x = – 160
8. x = – 400

Hence, the numerical value of temperature read by thermometers both in 0C and 0F scales becomes equal at – 400.
