can anyone tell me the proper ratio of how much round up to a gallon of water?

You should follow the directions included on the label. If you don't have it you should post the % of active ingredient (glyphosate); the different concentrations vary.

i know 41% glyphosate concentrate is generally recommended at 2-3 percent for most things on the label.

I use 3 oz. per gallon or 16 oz ( apint) to 5 gals water...

it makes no difference how much per gallon you mix it (within reason).

What matters is how much you put out per acre (gallons per acre).

If your sprayer puts out 20 gallons/acre - then you want 16-20 oz per 20 gallons-

If your sprayer puts out 40 gallons per acre - then you want to mix 16-20 oz per 40 gallons -

Get it?

What Farm-Hunter said. If you are just mixing 2-3 gal in a hand/tank sprayer, then just follow the label. The last time I used a 3 gal sprayer I added 7.5 oz of 51% Round-up per 3 gal tank.

This spring I used a 35gal srayer on a trailer with 5 spray nozzles on a fold out boom. 1. To figure the mix rate I first measured the time it took the ATV to travel 200ft in 1,2,3 gear, and calculated MPH. 2. Then measured the output of each spray nozzle in 1 min, and calculated Gallons/min. With nozzles spaced a standard 20 inches .... I sprayed about 20gal/acre in 2nd gear. Thus to apply 1 quart of round-up per acre, I add that to 20 gal water and spray away!
