US tablespoon and millilitre 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.
Exemple
1 US tbsp = 14.7867647812 mL · 10 US tbsp = 147.867647812 mL.
