Newtonian constant of gravitation

G = 6.674 30(15) × 10⁻¹¹ m³ kg⁻¹ s⁻²

Unit: m³ kg⁻¹ s⁻²
Value: 6.674 30(15) × 10⁻¹¹
Exact: no
Note: The worst-measured fundamental constant by far — gravity is too weak to pin down precisely.
Symbol: G
Category: Universal
Numeric: 6.6743e-11
Uncertainty: ±0.000 15 × 10⁻¹¹ (2.2 × 10⁻⁵ relative)
