• A quart is the equivalent of 946.35 cc's (cubic centimeters).

 

• 1500 cubic centimeters is equal to 50.72 fluid ounces (US) or 52.79 British fluid ounces

 

 There's 30 cc's in an oz., 32 oz. In a quart, so you have 960 cc's in a qt. You asked how many oz. In 1500 cc's so: 1500cc / 30cc = 50 oz.
That "/" is my divide sign btw...
