Discussion Overview

The discussion revolves around the conversion of 180 tons to kN/m, focusing on the compatibility of units and the context of their application, particularly in relation to forces on a bridge.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants assert that tons cannot be directly converted to kN/m, as kN/m represents a force distributed over a length, while tons can represent either force or mass.
  • Others clarify that while tons can be converted to kN, there is no distance provided to facilitate a conversion to kN/m.
  • A participant expresses a need for the conversion in the context of calculating the dead load of a bridge deck, suggesting that converting tons to kN and then dividing by the bridge length might be the correct approach.
  • Several participants request the formula related to the dead load calculation to better understand the context of the conversion.

Areas of Agreement / Disagreement

Participants generally agree that tons and kN/m are not directly compatible units, but there is no consensus on the best approach to address the conversion in the context of the bridge load calculation.

Contextual Notes

The discussion highlights the need for additional information, such as the specific formula for calculating the dead load, which remains unresolved.

Hello,

can anyone help me to convert 180 ton to kN/m ?
Which formula can you use to convert this?

Thanks!

You can't convert tons to kN/m. kN/m represents a force distributed over a length, while tons can either be an absolute force (or mass).

e.g., 1 metric ton = 1000 kg, while the ton in imperial units is 2240 pounds force (or 2000 pounds force for the so called short ton).
 
Welcome to PF!

I'm sorry, but those two units are not compatible. You can convert tons to kN (google will tell you how), but there is no distance in the first number to convert to meters.

Hi Laurine. Perhaps you could explain why you would like to do this conversion? --- then someone could help by examining the lead up to this question.

Hi everyone,
thanks for the reactions!

Well, we need to discribe the forces on a bridge. In one of the formulas, we need the dead load of the deck. I can only find the selfweight in tons, but the formula demands the unit [kN/m].
So I guess it would be correct if I convert tons in kN and than divide this by the total length of the bridge?

Kind regards
 
Can you post that formula here?

I'm sorry for my late anwer, but I've found the answer to my question. Thank you!
