Homologous temperature

Homologous temperature expresses the <a href="/facts/Thermodynamic_temperature/JXeJJPa6">thermodynamic temperature</a> of a material as a fraction of the thermodynamic temperature of its <a href="/facts/Melting_point/MY0w0h0k">melting point</a> (i.e. using the <a href="/facts/Kelvin_scale/E3trzC4C">Kelvin scale</a>):

For example, the homologous temperature of lead at room temperature (25 °C) is approximately 0.50 (TH = T/Tmp = 298 K/601 K = 0.50).
