Hello linux-iio@xxxxxxxxxxxxxxx,

In reference to:
https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-iio

There is this section:

What:		/sys/bus/iio/devices/iio:deviceX/in_pressureY_raw
What:		/sys/bus/iio/devices/iio:deviceX/in_pressure_raw
KernelVersion:	3.8
Contact:	linux-iio@xxxxxxxxxxxxxxx
Description:
		Raw pressure measurement from channel Y. Units after
		application of scale and offset are kilopascal.

What:		/sys/bus/iio/devices/iio:deviceX/in_pressureY_input
What:		/sys/bus/iio/devices/iio:deviceX/in_pressure_input
KernelVersion:	3.8
Contact:	linux-iio@xxxxxxxxxxxxxxx
Description:
		Scaled pressure measurement from channel Y, in kilopascal.

What:		/sys/bus/iio/devices/iio:deviceX/in_humidityrelative_raw
KernelVersion:	3.14
Contact:	linux-iio@xxxxxxxxxxxxxxx
Description:
		Raw humidity measurement of air. Units after application of
		scale and offset are milli percent.

What:		/sys/bus/iio/devices/iio:deviceX/in_humidityrelative_input
KernelVersion:	3.14

Description:
		Scaled humidity measurement in milli percent.

Nowhere do I find the unit kilopascal used in atmospheric pressure.
To stick with International System of Units and its Prefixes
https://en.wikipedia.org/wiki/International_System_of_Units#Prefixes

The standard unit for used in atmospheric pressure measurements or readings is the hectopascal (hPa), in meteorology, for atmospheric pressure, the modern equivalent of the traditional millibar.

What would it take to make this change to the standard for
https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-iio ?

Thank you.
