| Constant | Value | Unit | Source |
|---|---|---|---|
| Gravitational constant G | 6.67430 × 10⁻¹¹ | m³·kg⁻¹·s⁻² | CODATA 2018 recommended value (rel. std. unc. 2.2×10⁻⁵) |
| Speed of light in vacuum c | 299 792 458 | m·s⁻¹ | SI defining constant (exact) |
Note: c is an SI defining constant (exact); G follows CODATA 2018, whose uncertainty sets the precision ceiling of r_s.
