What is the value oo K. T. and china?

The value of K varies with temperature and pressure. At standard conditions (0°C and 1 atm), KT=1.38×10^-23 m^2 kg s^-2 K^-1.

The T in the equation is the thermodynamic temperature, measured in Kelvin. The thermodynamic temperature scale is an absolute temperature scale that uses the triple point of water as a fixed point, and it is equivalent to the Celsius temperature scale shifted by 273.15 degrees.

China is not a unit or a variable in the equation, so it does not have a value in this context.
