Great tool - user friendly and fit for purpose
I would recommend this property calculator for those wanting to check crude assay data, and those wanting to blend petroleum products. It has all the calculations you need, and the screen layouts have been well thought through. I would like to be able to blend Reid Vapour Pressure in kPa (rather than having to use psi), however this is only a tiny minor inconvenience for what is a unique and useful tool, available for your phone! - Geoffrey Gill
