Why the distinction matters
US liquid pint and Imperial fluid ounce belong to measurement conventions that may look familiar but are not always equivalent across countries. Mendeleev.com therefore keeps the system name next to the abbreviation and calculates from defined conversion factors rather than rounded kitchen rules.
Example
1 US pt = 16.6534836926 imp fl oz · 10 US pt = 166.534836926 imp fl oz.
