At 0 K according to -273,15°C the thermal energy and thus the oscillatory motion of the electrons and particles
come to stop. Therefore there is no lower temperature than -273,15°C, even if that can be entered here.

Comparison: Fahrenheit, Celsius - sengpielaudio

The degree centigrade (°C) was officially renamed Celsius in 1948 to avoid confusion
with the angular measure known as the centigrade (one hundredth of a grade).

Formula
9/5 = 1.8     9/4 = 2.25     10/8 = 1.25
Fahrenheit Celsius  C = (F − 32) / 1.8
Fahrenheit kelvin K = (F + 459.67) / 1.8
Fahrenheit Rankine  Ra =  F + 459.67
Fahrenheit Réaumur  Re = (F − 32) / 2.25
Celsius Fahrenheit  F =  C × 1.8 + 32
Celsius kelvin K = C + 273.15
Celsius Rankine  Ra =  C × 1.8 + 32 + 459.67
Celsius Réaumur  Re =  C × 0.8
kelvin Celsius  C = K − 273.15
kelvin Fahrenheit  F = K × 1.8 − 459.67
kelvin Rankine  Ra = K × 1.8
kelvin Réaumur  R = (K − 273.15) × 0.8
Rankine Celsius  C = (Ra − 32 − 459.67) / 1.8
Rankine Fahrenheit  F =  Ra − 459.67
Rankine kelvin K =  Ra / 1.8
Rankine Réaumur  Re = (Ra - 32 - 459.67) / 2.25
Réaumur Celsius  C =  Re × 1.25
Réaumur Fahrenheit  F =  Re × 2.25 + 32
Réaumur kelvin K =  Re × 1.25 + 273.15
