Kilogram meters squared per second to reduced Planck constants
Type a value in kg·m²/s to get it in ħ instantly.
9.483×10³³ħ
That's 1,000,000,000,000,000,000,000,000,000,000,000× as much as a rotating molecule, while a spinning bicycle wheel is 3× more. That is about 9.483×10³³ quanta of ħ.
Convert the other way: ħ to kg·m²/s
What it means
How much spin is that?
Angular momentum has the same dimensions as action, which is why the same constant, ħ, quantizes both.
The math
How to convert kg·m²/s to ħ
To convert kilogram meters squared per second to reduced Planck constants, multiply by 9.483×10³³.
Example: 1 kg·m²/s × 9.483×10³³ = 9.483×10³³ ħ.
In the other direction, 1 ħ = 1.055×10⁻³⁴ kg·m²/s.
