It is said that the original Centigrade thermometer designed by Celsius had upper fixed point (steam point) as $\text{0°}$ and lower fixed point (ice point) as $\text{100°}$. This temperature scale we label as Tuglak scale and temperatures in this scale represented by $\text{°T}$. A temperature of $50°\mathrm{T}$ is equivalent to $\mathrm{x}°\mathrm{C}$, then x is
