WebOct 10, 2024 · Before May 2024, Planck's constant was not defined by an exact value and instead was measured experimentally to be 6.626069934 ( 89) × 10 − 34 J ⋅ s. However, it is worth noting what we mean in saying that this constant has a certain numerical value when expressed in certain units. WebThe formula and the value were already known to Max Planck more than 100 years ago, that's why they're called Planck units. Unless there are very large or strangely warped extra dimensions in our spacetime, the Planck length is the minimum length scale that may be assigned the usual physical and geometric interpretation.

Planck's constant was formulated as part of Max Planck's successful effort to produce a mathematical expression that accurately predicted the observed spectral distribution of thermal radiation from a closed furnace (black-body radiation).
