Comment (by ychemin):
article is here for file mh_eto.c :
https://www.researchgate.net/profile/Peter_Droogers/publication/226830392_Estimating_Reference_Evapotranspiration_Under_Inaccurate_Data_Conditions/links/0f31753a0483fd97c0000000.pdf
ref to equation 5 page 40.
equation 1 page 36 references the units used: RA-> MJ / m2 / d
MegaJoules per meter square per day.
So the conversion is indeed wrong in the ticket.
