DrRheology can supply detailed calculation sheets where units are mixed, or require converting between systems in live calculation mode and in fixed content mode.
Disclaimer. When DrRheology supplies values as part of a project (calculation management or technical writing etc ), then the values used are fully qualified. DrRheology can supply certified values where these are required for a critical process. Otherwise, values supplied as above should be verified for critical applications.
