==> before going any further, make sure that you set the app to the mode most appropriate for you. Do you want to compute with a equal sign (ALG) or with a ENTER and stack (RPN)? Click on the button at top right, select "set-up" and toggle between RPN and ALG.

==>this app is feature rich, with over 360 defined units and constants, it could be seen as a challenge. Master it, and it will reward you. See the video at https://youtu.be/v17HhwJcCFc

Just like a high performance car, PolyUnitSMPL requires a bit of effort to fully master, but it is far more powerful than anything else out there.

PolyUnitSMPL does more than unit conversion, it calculates with units. PolyUnitSMPL will handle values expressed in different units and convert them on the fly to the specified dimensions. Values can be expressed using up to 10 simultaneous units. You have a pump generating a few inch of water pressure in a minute that needs converting to pounds per square inch per second? Need to see 3 meters is feet? Answer is 9feet, 10inches and 7/64th.

PolyUnitSMPL will handle it.

You have quotes for a product in Yen per kilogram and need to compare with a US based suppliers who gives it in US$ per pound? You convert that on the fly with PolyUnitSMPL.

Have a model railroad with plans for HO scale in inches and would need to find the conversion in mm for N scale? No need to calculate, just enter what it is and specify what you want it into!
