Enter the Planck’s constant and the uncertainty in position (m) into the Calculator. The calculator will evaluate the Minimum Uncertainty.

## Minimum Uncertainty Formula

up = h/(4*pi)/ ux

Variables:

- up is the Minimum Uncertainty ((momentum uncertainty, m))
- h is the Planck’s constant
- ux is the uncertainty in position (m)

To calculate Minimum Uncertainty, divide Planck’s constant by 4 times pi, then divide by the uncertainty in position.

## How to Calculate Minimum Uncertainty?

The following steps outline how to calculate the Minimum Uncertainty.

- First, determine the Planck’s constant.
- Next, determine the uncertainty in position (m).
- Next, gather the formula from above = up = h/(4*pi)/ ux.
- Finally, calculate the Minimum Uncertainty.
- After inserting the variables and calculating the result, check your answer with the calculator above.
