can someone help me to convert pascal unit to voltage please ?

That doesn't make sense: it's like trying to convert hamburgers to oak trees.

The Pascal (Pa) is a unit of pressure (N/m² or Newton per square meter) while a voltage is expressed in Volt (V equivalent to W/A [Watt per Ampère]), all in the SI system. Dimensional equation for Pa is L⁻¹ M T⁻² which is very different from the V which is L² M T⁻³ I⁻¹.

The device often used to convert pressure to voltage is a strain jauge.

Exactly what I said!

The page you mention explains the obvious way to handle in software a given linear pressure sensor. The output of the device is expressed in V/psi (a psi is a ad-hoc pressure unit) and the text explains how to recover the pressure applied from the measure and linear scaling parameters.

If the explanations given there aren't clear to you, tell us what you don't understand. Else please tell us in full what you have, what you tried and how the results deviate from what you expect.
