I didn't see one. If you click on the ugly three lines (misnamed 'hamburger') at upper left, you do find a useful array of conversion types. But you cannot use the 8.1's calculator (which yes is better), in 10. When I tried, I got a claim that the dll it needed to run,wasn't available, and it wouldn't tell me WHAT dll, was missing. (I dual boot 8.1 with 10.)
Windows 7 calc.exe won't work, either. XP's version might, but it's so ugly and sparse I didn't want to try it. The file is in Windows System32, and also in Windows System32 dllcache .
Sent feedback via Insider program saying bluntly the calculator in 10 looked like a tombstone and was too big for laptops.
