Formula and unit definitions

Convert angular momentum units used in classical mechanics and physics.

target value = source value × source factor ÷ target factor

Source unit: Planck constant (h), factor 6.62607015e-34, offset 0.

Target unit: millijoule second (mJ-s), factor 0.001, offset 0.

Important note

The calculation is performed locally from the listed unit definitions. Display results are rounded for readability; high-precision and regulated work should use the governing standard and appropriate significant figures.

For high-precision, regulated or safety-critical use, check the underlying standard and its required precision. Historical and approximate units are identified in their names or family descriptions.
