Fluid ounces and teaspoons

Fluid ounces and teaspoons are both volume units.

A fluid ounce is abbreviated as fl oz or oz fl, a teaspoon - a simple teaspoon, and sometimes t, ts, or tspn.

Liquid ounces differ from dry ounces, units of weight used to measure dry ingredients.

A teaspoon is a US customary system unit of volume. It is used to measure liquid substances. So, what is a teaspoon value?

1 US teaspoon = ⅓ tablespoon, 0.02 cup, 0.166667 fluid ounces, 0.01 US liquid pint, or 4.9 milliliters.

In nutrition labeling and pharmaceutic prescriptions, 1 US teaspoon equals 5 milliliters.

1 metric teaspoon equals 5 ml.

1 Imperial teaspoon = ⅓ Imperial tablespoons, 0.02 Imperial cup, 0.2 Imperial fluid ounces, 0.01 Imperial pint, or 5.9 milliliters.

1 Australian teaspoon = ¼ tablespoon or 5 ml.

A fluid ounce, also known as a regular ounce, is a United States customary and Imperial unit of volume.

How much is a fluid ounce?

1 US fl oz = 1/128 US gallon, 1/32 US quart, 1/16 US pint, ⅛ US cup, 2 US tablespoons, or 6 US teaspoons.

One fl oz Imperial = 0.00625 Imperial gallon, 1/40 Imperial quart, 1/20 Imperial pint, 1/10 Imperial cup, 1.6 Imperial tablespoons, or 4.8 Imperial teaspoons.
