Quarts to Fluid Ounces formula
To convert quarts to fluid ounces, multiply by 32.
fl oz = qt × 32
Put another way, one quart is exactly 32 fluid ounces.
Why this factor: the quart and the fluid ounce are both defined against the liter, so dividing one definition by the other gives 32 directly. Both definitions are set out in full below.
To go the other way, divide by 32 — or use the Fluid Ounces to Quarts converter, which is the same calculation reversed.
