Reliable Unit Conversion Tool

Problem/Challenge - John Beath Environmental & Sustainability Consultants

Problem/Challenge:

  • Calculations that require unit conversions are often embedded in complex formulas and therefore difficult to check

  • More often than acceptable, the inverse of the proper conversion is accidentally applied

Solution - John Beath Environmental & Sustainability Consultants

Solution:

  • EPA’s AP-42 started the process with a good format for factors

  • JBE has converted this into an interactive tool that can select and deliver to a worksheet

  • The EPA factor list did not contain all instances where there was a “from A to B,” and also a “from B to A,” so we added them to the table using reciprocals – now the list is much more useful

  • By using the tool, the choice of the right factor is displayed in a standard way

 Benefits:

  • Only having the factor appear in one place will reduce error potential

  • Following this work practice will reduce QA time by reviewers

  • Reducing errors in calculations will have a significant impact
