How this calculator works
The form on this page is a Torr-to-Atmosphere converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the atm result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
