When I was an Android user I found a fantastic free app call Convertbee and it converted pretty much any unit to any other unit you can imagine. It also did currency.
Since I switched to iOS full time I have not found a great replacement. I have been using Units Plus and went to pay for your full version, however it has not had an update in 2+ years and I worry about it being abandoned (looking at you Bean for Lemmy).
Looking for a replacement app available in the US. Thanks.
ETA: I have no issue paying for the app, but absolutely no subscriptions.
You can use spotlight to do most of these conversions
Soulver for iPad can do that. It’s very good, but expensive.
notepad calculator app for Mac & iPad that gives instant answers to calculations in your text.
It is a better way to work things out than a traditional calculator, and a more lightweight tool for working through problems than a spreadsheet.
