R&D Use

Four senior R&D execs in our company use it and have never had a problem in F or C. Easy conversion and more flexible than most other apps. There is a small error near 0degF and tiny inconsistencies near saturation but these would only be noticed by a scientist. Great app. Is it available for Excel?
