A feature a iOS 16 and iPadOS 16 about which less has been said, is the converter of units of measurement (units converter in iOS 16).
If up to this version of iOS I needed a separate application to We make the conversion between the imperial and metric measurement units (Metric and Imperial), now it is sufficient to keep pressed on the text in which we have the values.
The value of a temperature expressed in degrees Celsius, Fahrenheit or Kelvin sent in a text message (Messages) or saved in a note of Note, can be transformed into any of the three units of measure.

To make the transformation of an imperial value in Metric Or vice versa, all we have to do is hold the value of the text. If we want to do transformation from degrees Fahrenheit in Celsius or Kelvin From a text, we hold value. Units converter will open with the transformation of value.

In the same way we can transform a value expressed in the unit of measure feet (ft - feet) in meters (m), centimeters (cm), millimeter (mm), yellow (yd) or inch (in).
Speed expressed in miles per hour (km/h) in miles per hour (mph) or meters per second (m/s).

This units converter in iOS 16 is available in applications Notes and Messages. This capability may appear in other applications, such as Compass, where Changing the units of measurement Metric or Imperial It depends on the language in which the operating system is set.
This characteristic of iOS 16 and iPadOS 16 will drastically reduce the download of applications units converter for iPhone and iPad FROM App Store. Currently I have not seen that this feature work on macOS Ventura.
