Unit Conversions in the 21st Century: Insights into a Routine yet Critical Scientific and Engineering Task as Measured through User Interactions with a Mobile App
Abstract
There appears to be no published knowledge regarding how humans use unit conversions. Until very recently, acquiring such data would be essentially impossible, but mobile devices have now enabled many questions to be answered through passive “crowdsourcing” of big data sets. This work details the analysis of five years of anonymous user data collected from a unit converter mobile application utilized by nearly 50,000 users in 210 countries to perform ~870,000 calculations over that period.
