Is gravity in Forgotten Realms the same strength as Earth? I’m doing calculations to find the exact weights of coins in Waterdeep Toril is SLIGHTLY larger than Earth, so the gravity is SLIGHTLY heavier, but the difference is so tiny that the PHB 50 coins to the pound works just fine. (The potentially greater difference is offset by Toril having less mass/different core composition.)#Realmslore

A larger planet may have greater gravitational pull but isn’t the question really about the force of gravity at the surface, which is inversely proportional to the square of the radius of the sphere?
Newton’s universal law of gravitation: F = (G*m1*m2)/r^2
m1 would be you the person, m2 is the planet, and r is the distance between your centers of mass. If the mass and radius of the planet are changed the net ratio could remain the same even if the gravitational constant G changed as well.
