Thermodynamic beta has units reciprocal to that of energy (in SI units, reciprocal joules, [ β β ] = J − − 1 ). In non-thermal units, it can also be measured in byte per joule, or more conveniently, gigabyte per nanojoule; 1 K is equivalent to about 13,062 gigabytes per nanojoule; at room temperature: T = 300K, β ≈ 44 GB/nJ ≈ 39 eV ≈ 2.4 × 10 J. The conversion factor is 1 GB/nJ = 8 ln ⁡ ⁡ 2 × × 10 18 J.
