Designed for Windows 10 Mobile devices, this is a handy, portable, and friendly SI and IP units converter tool for variables commonly used in the HVAC industry. There are 126 variables listed alphabetically; e.g., from (Btu to Megajoule), (psi to kiloPascals), (cubic yards to cubic meters) plus 123 more. The App allows entry of values in either set of units (SI or IP) and those values are automatically converted th the opposite set of units.

The conversion parameters are based on ASHRAE’s (American Society of Heating, Refrigerating, and Air-conditioning Engineers, Inc.) Guide, entitled “SI for HVAC&R”, published in 1997 and 2013.
