math conversion?

[jc207]

Can you convert psi or bar to lbs? I have a hydraulic load cell that reads psi and bar and trying to figure weight with it.

[Pistol]

PSI is a pressure measurement, not weight, so I don't know that you can convert it, but I am sure there is an engineer that can help

[ItsLeo]

Put a known weight on it. Read the psi.

Divide the known weight by the psi read. This is your conversion factor.

Now when you put the unknown weight on it read the psi and multiply that by your conversion factor. That will give you the answer in LBS.

It won't be very accurate but you'll get a rough estimate.

[lab man]

A bar = 14.50377 psi
If you can figure out the area that the pressure is working against (sq in) then multiply it by the psi.

Weight (pounds)= Pounds per square inch X square inches (area where load is applied)

I have the same calculator as you!!!

This may help...



This chart will only work on a straight line pull though. If you double line or use some sort of tong you'll have to do the math on that.

You can figure force in lbs. Just need the piston size

Example: If your load cell has a 5" piston and you apply 1000 psi of hydraulic pressure you're applying 19,634 lbs. of force.

Is that what you are looking for?

Here is a web page that may help:

Just put in the number and what you want to convert from and into

[texas shag]

multiply your pressure reading (in PSI) by the cross sectional area of you load cell (in Sq. In.). That will give you the pounds force, which is the same as pounds mass on earth.

Finally heard back from my dad, who is a rocket engineer. This is what he wrote:
Lbs is weight
Psi is pounds per square inches. Which is pressure.
Bars is meteoric conversion of pressure.
The answer is no.

But Jaybo may have figured out what you were asking for- pounds of force

Put a known weight on it. Read the psi.

Divide the known weight by the psi read. This is your conversion factor.

Now when you put the unknown weight on it read the psi and multiply that by your conversion factor. That will give you the answer in LBS.

It won't be very accurate but you'll get a rough estimate.

We've had to do this, until we goy the cat line conversion chart. Finally just started using 2300 psi, it gets in the ballpark of 15000# of pull. Never found anything definitive just ballpark numbers.

If I wasn't so lazy I would load this beam and take it to the scale

So once on the load cell the gauge reads 625 psi / 43 bars...what is the weight in lbs?
