Why the distinction matters
Imperial pint and US teaspoon 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 imp pt = 115.291192848 US tsp · 10 imp pt = 1 152.91193 US tsp.
115.291192848 US tsp
