Tons = Ounces

[Anonymous]

Can someone tell me what the equasion would be to figure out HO car weights for tonnage.......for example, a 5 ounce car weighs x amount of tons......and a 100 ton car weighs x ounces. thanks............Jamie

Mass doesn't scale the same way dimensions scale. There is an RP for car weight in HO. I think it is something like one ounce + half-ounce per inch.

Thanks for the reply Ed. I'm not looking for the NMRA recomended weights, I was thinking of a few test car that would simulate a fully loaded gondola or hopper which usually carry around 100 tons in them. Just one of those crazy ideas I had..................Jamie

Hi Jamie;

Mass is a volume dimension, so you have to cube the scale. So you need to multiply of divide by 87 cubed = 658503.

You will find that the NMRA RP's are pretty close for box cars under 50ft.

Using the cube, a ton works out to just under .05 ounces.

One metric tonne = 2000 pounds, plus 200 pounds of European attitude.( I believe it's about 100 pounds each from France & Germany.)
