An improved electronic determination of the Boltzmann constant by Johnson noise thermometry. Metrologia, 2017; DOI: 10.1088/1681-7575/aa781e ...

Denoted by the symbol k, the Boltzmann constant is ubiquitous throughout physics calculations that involve temperature and entropy. ampere (electric current): André-Marie Ampère, who is often ...

So researchers have been pursuing a variety of methods for measuring the Boltzmann constant. The most accurate method remains measurements of the acoustical properties of a gas.

Then divide this sum by Boltzmann’s constant to get the temperature. This comes out to about 10 94 kelvin. While this is a large number, it certainly isn’t infinite.
