Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10-23 J K-1.The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule).
This is exactly the value estimated by the formula stated earlier. EXAMPLE: Torque applied at different diameters , K v (rpm/V) {\displaystyle K_{\text{v (rpm/V)}}} = 3600 rpm/V ≈ 377 rad/s/V , K T {\displaystyle K_{\text{T}}} ≈ 0.00265 N.m/A (each calculatable if one is known) , V = 2 v, I a {\displaystyle I_{\text{a}}} = 2 A, P = 4 W ...
SI temperature/coldness conversion scale: Temperatures in Kelvin scale are shown in blue (Celsius scale in green, Fahrenheit scale in red), coldness values in gigabyte per nanojoule are shown in black. Infinite temperature (coldness zero) is shown at the top of the diagram; positive values of coldness/temperature are on the right-hand side ...

kT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on E ...
President Joe Biden urged Congress to pass 'commonsense' gun-safety laws following Wisconsin school shooting that killed two and wounded six others
If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k. A triangle whose side lengths are a Pythagorean triple is a right triangle and called a Pythagorean triangle. A primitive Pythagorean triple is one in which a, b and c are coprime (that is, they have no common divisor larger than 1). [1]
