A pint contains different amounts of fluid ounces depending on the measurement system:
- In the United States customary system, a liquid pint is equal to 16 fluid ounces
- In the British Imperial system, a pint is larger and equals 20 fluid ounces
Thus, a U.S. pint is 16 fluid ounces, while a U.K. (Imperial) pint is 20 fluid ounces. This difference arises from the distinct definitions of the gallon and fluid ounce in each system
