Temperature calculus

Calculate the percentage of temperature increase if changed from 18°C to 33°C?

Correct answer:

p =  5.152 %

Step-by-step explanation:

$$\begin{gathered} t_1=18\text{ °C } \\ {t}_2=33\text{ °C } \\ {T}_1=273.15+t_1=273.15+18={\displaystyle \frac{5823}{20}}=291.15\text{ K } \\ {T}_2=273.15+t_2=273.15+33={\displaystyle \frac{6123}{20}}=306.15\text{ K } \\ p=100\cdot {\displaystyle \frac{T_2-T_1}{T_1}}=100\cdot {\displaystyle \frac{306.15-291.15}{291.15}}=5.152\mathrm{\%} \end{gathered}$$

I think that percent change of temperature is made in Kelvins (absolute temperature).
