iOS 18: Overhauled Calculator App Supports These 15 Conversions

During its WWDC 2024 keynote on Monday, Apple introduced a new Calculator app for iPad that includes a new Math Notes feature, and there are similar changes to be found in the Calculator app in iOS 18.

The Calculator app on iPhone now has an additional button to switch between Basic, Scientific, and Math Notes in portrait or landscape view. Meanwhile, there's a useful new History feature that helps you keep track of previous calculations.

In addition, a new Convert option supports unit conversions for length, weight, currencies, and more. Here's the full conversions that are supported:

  • Angle
  • Area
  • Currency
  • Data
  • Energy
  • Force
  • Fuel
  • Length
  • Power
  • Pressure
  • Speed
  • Temperature
  • Time
  • Volume
  • Weight

In iPadOS 18, the new Calculator app lets users type or write out mathematical expressions with an Apple Pencil and see them solved in their own handwriting. These Math Notes are automatically accessible in the Notes app in a new Math Notes folder that can be accessed on both iPhone and iPad.

The first developer beta of iPadOS 18 is now available, with a public beta following in July, and official release to the public in the fall.

If Apple wants to give us a new calculator, why not give us the opportunity to set it up for Reverse Polish Notation (RPN). Been using these types of calculators since HP released them in the 70s. It is a whole lot more efficient than any TI style calculator where you have to use parenthesis.

I know there are RPN calculators apps that can be downloaded. But it would be nice to get an official Apple version.

Also integrated with Notes and other apps ?

Only thing I miss is "Programmer mode" as the one in OSX.

Agree. If this new iOS Calculator doesn't have RPN then it's mostly a waste of Apple's time and mine. The MacOS Calculator has had it for years.

I think most people doing conversions will just stay within a web browser… most search engines have pretty decent and updated conversion tools.

It’s nice to have in the app still.
