Converting from Voltage input to pund force

[kokowawa]

The program reads voltage that is changing with time .. but from testing i have a table of pound force VS voltage .. SO how can i calculate the voltage input ( thats always changing with time ) and convert that value to pound force.

Is it linear?

y=mx+b ???

Use the express vi "Scaling and Mapping" in the "Signal Operation" palett and choose "interpolated". You can then define your table and use the vi to convert your readings fr any voltage.
