iOS 18: Perform Calculations and Conversions in Messages

In iOS 18, there's a handy new feature in the Messages app that allows you to perform quick math calculations and conversions without leaving your conversations. The feature is thanks to the new system-wide Math Notes functionality, which is integrated into Messages, providing a seamless way to solve equations and convert units on the fly.

With iOS 18, you can say goodbye to switching between apps or reaching for a calculator when discussing numbers or currencies in your chats. The feature works by automatically detecting mathematical expressions and currencies, providing instant results within the message composition field or with a tap.

To use Math Notes in Messages, simply type an equation or conversion request followed by an equals sign. The system then instantly calculates the result, streamlining communication when sharing costs, splitting bills, or discussing measurements with friends and family. To get a foreign currency conversion, simply double tap the amount to view a conversion in your local currency in the popup menu. It's that easy.
