How To Convert US Quart to Imperial Pint
Formula: imperial pints = US quarts × 1.66535
Example: Convert 3 US qt to imperial pints.
3 × 1.66535 = 4.99605 imp pt.
To do it by hand, take your US quart value and multiply by 1.66535. This works because a US quart is smaller than a UK imperial quart, so it becomes more imperial pints.

Real Life Examples
These examples show where US quarts and imperial pints often get mixed, and how to convert safely.
- US soup recipe for a UK kitchen: A recipe calls for 2 US qt of broth. In imperial pints, that is 2 × 1.66535 = 3.33070 imp pt, so you can measure using a UK pint jug.
