Measurement system: US customary → US customary

Convert US teaspoon (US tsp) → US fluid ounce (US fl oz)

1 US tsp equals 0.166666666667 US fl oz. The name of a customary unit matters: US liquid and Imperial units are not interchangeable. US teaspoon (US tsp) is shown explicitly so a reader can recognize the term used in recipes and measuring tools.

Why the distinction matters

US teaspoon and US 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 tsp = 0.166666666667 US fl oz · 10 US tsp = 1.66666666667 US fl oz.
