Default ECMWF wind speed ?

All very pretty , such images as 10m wind speed on
https://www.ecmwf.int/en/forecasts/charts/catalogue
but next to useless without reference to the constant of proportionality
of pixel length to knots/kph/mph/mps or whatever of the wind arrows. Why
no conventional wind barbs , if they have to confuse it all with
temperature ?
Try googling gets nowhere as to an ECMWF explainer. Anyone been here
before and knows the constant of proportionality or do I have to compare
to GFS isotachs for say 19 Jan, the next locally high wind regime.? Is
it even a linear scale?
