Heisenberg Uncertainty Principle Calculator
Calculate the minimum uncertainty in one variable given the uncertainty in its conjugate partner.
Results
Minimum Momentum Uncertainty (Δp): 5.2729e-25 kg·m/s
Minimum Product (ℏ/2): 5.2729e-35 J·s
Formulas
Position-Momentum: ΔxΔp ≥ ℏ/2
Energy-Time: ΔEΔt ≥ ℏ/2
ℏ = h/(2π) = 1.054571817 × 10⁻³⁴ J·s
