Dear Sir,

I have distillation data and specific gravity details for Some Grades of Oil like 7 diff Grades of Oil available with me. I want to fit Curve Fitting mathematical equation for this data to get final equation for each grade of oil. So When user chooses any grade of oil from dropdown, here, i want to select any equation which is fitted for the data for that oil .

How to do this in excel ?? Please advice on this from all expert users now.

Thanks.

Best Regards,
