Hi,
Sorry for the delay, we wanted to confirm with the developer of the product.
"The kg/m2/8day units are equivalent to mm/8day. Therefore, you just need to apply the 0.1 scale factor to get ET in the desired mm/8day units as noted below. As a check, the typical ET rate over a humid temperate grassland in summer would be ~1-4 mm/day."
Thanks,
Brett

Hi @valeria_22 ,

Above we listed the answer for mm/8 day, so you would just need to divide by 8 to get mm/day. However, if you are interested in ~daily data you might be interested in ECOSTRESS ET data which can be found here: https://lpdaac.usgs.gov/product_search/?query=ecostress&keyword=Evapotranspiration+%28ET%29&status=Operational&view=cards&sort=title
