When booze went metric the closest equivalent of the fifth (fifth of a gallon) is .750ml and of the quart (quarter gallon) is 1.0 liter. It took a while to get out of the habit of saying "give me a fifth" and I still refer to the smaller bottles as a pint or half pint.

So...you could substitute as above or if you want to be extremely exact a quart = 946.35ml and a fifth = 757.08ml.
