    How do I convert a one gallon recipe to five gallon all grain batch, do I just multiply by five?

    That is the easiest way to do it and plenty of people use this method. I think I remember reading that your hop utilization will decrease slightly, but I have no info to back that up.

    Yep. I'd second checking your IBUs on an online hop calculator. Plan on boiling off a gallon to a gallon and a half from your boil.

    Usually the one gallon commercial recipe uses 1 oz multiplication of hops, because of packing less then one Oz will not cost the same as the hops.
    When I started one gallon recipe , on my second batch I cut the hops by 1/3, when I start brewing 5 gallons I realize that 5 gallon batches can use less then one OZ hops.

    To summarize all that use brewing software , plus use common sense and adjust any recipe with your brewing software.

    Easiest way to do this is calculate your ingredients based on a percentage. Then as you scale your recipes the percentages will not change, but the total amount will.

    At homebrew scales, directly proportional scaling seems to be the way to go.

    You specify your target 5 gal batch as being all grain. Was your one gal batch extract? This could be a very different case.

    1/8 pound crystal 60

    1/2 ounce citra at boil

    I have scaled from 1:5 and 5:1 gallons an used linear conversion both ways. You will be a little off on hop utilization but not so much you should tear apart the recipe and recreate it to scale up or down.
