The biggest thing I'd want from a calculator -- having to calculate numeric expressions involving units, and getting the result in a specific unit. This is something I've used the google search prompt for because it can do these things to some degree, but google isn't a calculator and it will refuse to give you an answer right away if it doesn't think you entered a valid numeric expression.
Most of the time I'm looking for an answer in questions like:
4 weeks + 59*3 hours in days
1/2 * 36g * (900 m/s)^2 in joules
Other times when I'm working with memory and want to get a specific finite representation in hexadecimal:
1 megabyte as hex
This might be off-topic because you're building a suite of calculators that I'd have to switch between to perform these tasks, rather than a single calculator that can do all / most of these things, but this kinda raises a point - if you want to switch between the calculators, maybe the UI should allow going from one to the other without performing the navigation, I'm thinking something like a sidebar that you can click on to switch to a different calculator.
Ideally when you switch and switch back the state should be saved because you might need to copy multiple values between calculators. EDIT: I forgot browsers have tabs, but still.
But really for me personally, nothing would beat a single thing that can do units and bases
