Heisenberg Uncertainty Principle Calculator

Calculate the minimum uncertainty in one variable given the uncertainty in its conjugate partner.

Uncertainty Type

Position Uncertainty Δx (m)

Minimum Momentum Uncertainty (Δp): 5.2729e-25 kg·m/s

Minimum Product (ℏ/2): 5.2729e-35 J·s

Position-Momentum: ΔxΔp ≥ ℏ/2

Energy-Time: ΔEΔt ≥ ℏ/2

ℏ = h/(2π) = 1.054571817 × 10⁻³⁴ J·s
