🔬 Formula Breakdown to SI Units

entropy_flux_density = joule × kelvin
joule = newton × meter
newton = acceleration × kilogram
acceleration = meter × second_squared
second_squared = second × second
joule = rest_energy × rest_energy
rest_energy = kilogram × c_squared
c_squared = meter_squared × second_squared
meter_squared = meter × meter
joule = magnetic_dipole_moment × tesla
magnetic_dipole_moment = ampere × meter_squared
magnetic_dipole_moment = magnetization × meter_cubed
magnetization = ampere × meter
meter_cubed = meter_squared × meter
tesla = weber × meter_squared
weber = volt × second
volt = watt × ampere
watt = joule × second
watt = specific_power × kilogram
specific_power = meter_squared × second_cubed
second_cubed = second_squared × second
specific_power = velocity × acceleration
velocity = meter × second
specific_power = velocity_squared × second
velocity_squared = velocity × velocity
volt = joule × coulomb
coulomb = ampere × second
tesla = kram × ampere
kram = newton × meter

📜 Historical Background

History

Entropy (J/K) was introduced in classical thermodynamics (notably by Clausius) as a state function describing irreversibility and the directionality of spontaneous processes. Flux formulations came later with non-equilibrium thermodynamics and transport theory.
