O Scale is 1.81458 times the linear dimension of HO Scale. (87.1/ 48)
This is in just one dimension, say Length.
In Area, O scale is 1.81458 x 1.81458 times the area of HO, or 3.2927 times as big.
In Volume and Weight, O scale is 1.81458 x 1.81458 x 1.81458 or 5.9748686 times the volume and weight of HO Scale.
Thus, a locomotive or piece of rolling stock in O-Scale 2-Rail will weigh about 6 times as much as in HO, if it were modeled exactly.
