A little perspective
Gravitational attraction between two people one metre apart vs Earth-Moon L1 tidal acceleration over one kilometre: weight comparison
The gravitational attraction between two people one metre apart is about 3.74 times the Earth–Moon L1 tidal acceleration over one kilometre.
FORCE
This is the gravitational force that two people exert on each other when separated by one metre.
Earth-Moon L1 tidal acceleration over one kilometre is the difference in gravitational pull experienced across a one-kilometre distance near the Earth-Moon L1 point.

Defined examples — our methodology
The marked force is calibrated. Unmeasured illustration details are representative.
Earth-Moon L1 tidal acceleration over one kilometre
Equivalent differential force on a 1 kg body: 8.03 × 10⁻⁸ N; derived model; range 6 × 10⁻⁸ N–1 × 10⁻⁷ N.
About 8.03 x 10^-8 m/s2 difference across a 1 km radial baseline near Earth-Moon L1, expressed as equivalent force on a defined 1 kg body. Orientation and ephemeris change the result.
