The gravitational constant G in CGS and other units
G is measured, not defined, so every value below carries the same relative uncertainty as the SI value: about 22 parts per million. Only the leading digits are meaningful.

| cm3·g−1·s−2 CGS: cubic centimetres per gram per second squared | 6.6743 × 10−8 | |
| N·m2·kg−2 newton square metres per square kilogram | 6.6743 × 10−11 | |
| km3·kg−1·s−2 cubic kilometres per kilogram per second squared | 6.6743 × 10−20 | |
| ft3·lb−1·s−2 cubic feet per pound per second squared | 1.069 12 × 10−9 | |

How it is computed: 6.674 30 × 10⁻¹¹ m³ kg⁻¹ s⁻² × (100 cm/m)³ ÷ (1000 g/kg) = 6.6743 × 10−8.
All values computed from the CODATA 2022 value and unit definitions (SI Brochure, NIST SP 811). Exact values are rounded only for display. Checks.
