Change data format of sensors that is being send

Hi,

I succesfully installerd the Pimoroni weather hat on my raspberry pi 3B.
Its now sending my anemometer (wind strengt and direction) to my adafrui IO account.
The readings are in mps and the direction is North/North-East/East/ect.

I would like to readings to be changed
-from mps to “knots”
-From North also in the format in degrees like : North 10 degrees if possible with an arrow indicating the direction.

Does anyone know where/what/how to change this or has done this before?
