Give users a choice when changing unit systems to either dimensionally transform values based on the new units, or to keep values the same
Changing the unit system automatically scales all numbers. This is often not the user's intention: they want to change units from μM to nM, and they do not expect the concentration change from 1 μM to 1000 nM.
Quick solution: when clicking on "OK" in Select new unit system, give a warning: "All parameter values will be scaled to keep the physical meaning the same, e.g. the parameter wth the value of 1 uM in uM unit system will have the value 1000 nM in nM unit system".
Full solution: Add a checkbox "Scale the values of all parameters to keep the physical meaning the same: the parameter wth the value of 1 uM will have the value 1000 nM". When the checkbox is not checked, no values will be scaled.
A better implementation would be a radio button that users must select an option from, before they are able to hit "OK" and confirm the choice.
Also: While the text for the radio buttons should be simple, we can embed a "?" box, that when clicked will give a full explanation of the choice to make.
here are some words for the 2 radio buttons:
- transform all current values from the current units to the new units
- maintain all current values and only change unit labels.
