Heisenberg’s Uncertainty Principle Calculator: Understanding the Quantum World
About
The Heisenberg Uncertainty Principle lies at the core of quantum mechanics, highlighting the fundamental limits of measurement at atomic scales. This principle asserts that the more precisely we measure one property of a particle, such as its position, the less precisely we can know another property, like its momentum. Understanding this principle is essential for students, researchers, and professionals in physics and related disciplines. Our Heisenberg’s Uncertainty Principle Calculator is designed to simplify the application of this concept, allowing users to compute uncertainty values efficiently.

Instantly, the calculator will provide the uncertainty in your measurements, illustrating the principles of quantum physics in action!
Formula
The Heisenberg Uncertainty Principle is typically expressed in the form:
Δx * Δp ≥ ℏ / 2
Where:
- Δx = uncertainty in position
- Δp = uncertainty in momentum
- ℏ = reduced Planck’s constant (approximately 1.055 x 10-34 Js)
This equation signifies that the product of the uncertainties in measurements of position and momentum is at least as large as half of the reduced Planck’s constant.
Example Calculation
Let’s say we measured the position of an electron as follows:
- Δx (uncertainty in position) = 1 x 10-10 m
If we want to find the uncertainty in momentum (Δp), we can rearrange the formula:
Δp = ℏ / (2 * Δx)
Inserting our values:
Δp = 1.055 x 10-34 Js / (2 * 1 x 10-10 m)
Calculating this gives us an uncertainty in momentum of approximately:
Δp ≈ 5.275 x 10-25 kg·m/s
This calculation exemplifies how the uncertainties in measurements can drastically impact quantum phenomena.
Limitations
While the Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics, it has its limitations:
- The principle applies strictly at quantum scales and does not have significant implications for macroscopic objects.
