I am working on a conversion equation to put into the PLC that is running our refrigeration system. I have found the equation to convert temp to pressure, but i am struggling on finding the inverse of this equation. Any advice on a formula or method would be greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

y = .000044x3 + 0.0065x2 + 0.730x + 15.7
