Why cooks need both pint systems
Recipe writers don’t always specify which pint they mean. A British cookbook calling for “1 pint of milk” expects 20 fl oz. An American one expects 16 fl oz.
The formulas
- US pint: divide fluid ounces by 16
- Imperial pint: divide fluid ounces by 20
Example: 24 fl oz of stock
- US: 24 ÷ 16 = 1.5 pt
- Imperial: 24 ÷ 20 = 1.2 pt
Practical tips
- When in doubt, use fluid ounces. They’re unambiguous.
- Scale proportionally. If a recipe serves 4 and you need 6, multiply all liquid volumes by 1.5.
- Round sensibly. Two decimal places is plenty for home cooking.
Common kitchen amounts
- 8 fl oz = ½ US pt or 0.4 Imperial pt
- 16 fl oz = 1 US pt or 0.8 Imperial pt
- 32 fl oz = 2 US pt or 1.6 Imperial pt
