Converting ERA5-Land surface solar radiation downwards from J/m**2 to W/m**2

I have downloaded the surface solar radiation downwards data from the ERA5-Land dataset and I need to convert from J/m**2 to W/m**2.  I thought I could just divide the values by 3600 since the data are at hourly timesteps but the results are much too high (about 6 times top of atmosphere radiation). Can someone please share the appropriate accumulation period for these solar radiation data?


Thanks!

How about you check this Conversion table for accumulated variables (total precipitation/fluxes)

Hope this helps!
