Hi gwpriester,
it is planned to offer some kind of widgets so designers can embed/include some calculation or categories to the web-page. This will come in a future version and I'll let you know when it is done!
Regarding the conversion you mentioned. Could you be a little bit more precise? What exactly did you enter and what do you mean that nothing happens? Normally when you start typing on CalculatePlus search box like "500,000 Japa" there should be already be shown some suggestions and when you type further the correct item will appear when hitting the search box or click on the suggestion. For me this works just fine! :-)
best
Henry
