Looking for some help please if anyone knows...
I'm looking to convert 410 bar to metric tonne.
I worked it out as 57.75t after i think converting to lb/ft2.
If anyone can help it would be appreciated.
As S-J says we need a value for the area over which the pressure is applied.
Bar is a pressure.
What is the load cell/pressure gauge set up? It is impossible to calculate a force, mass or weight from a pressure without knowing an area.
I would be tempted to write my own programme for it, known weight reads "x amount of bar" on the gauge, repeat for lighter/heavier weights.
Of course, weight is a force with unit Newtons...
Thanks for all the replies, I’ll look in to the load cell issue In more detail tomorrow.
It’s a new rig I’m on, so unsure how they have got the figure they have, they don’t seem to know themselves, so I want to get it sorted as the calculations need to be accurate.

I’ve since found out there is a programme that the company have which gives the weight to the pressure based on the area.
I’m not fully convinced the weight is correct, I’m only a guest on here so will leave it as it is.
Thanks for all the replies and help.

If you think it is well-out by their calculation - can you not try it with a known weight on the crane?
We used to check against the crane loadcell with the forklift to see they both coincided or a known-weight container.
It’s a BOP tensioning system.
I’ve always seen a weight on the gauge until now, it’s a new one on me after 13 years!!

Blow Out Preventer for those that might be wondering.
Is a blow out preventer a pressure release valve?
No, it holds pressure.
