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?


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

Hope this helps!
