Conversion between teaspoons and fluid ounces is governed by precise mathematical and physical standards.
Because both units belong to the same dimensional category (volume), this conversion uses a fixed mathematical ratio that never changes regardless of ingredient temperature or density.
Direct (tsp to fl oz):
fl oz = teaspoons ÷ 6 (or tsp × 0.16667)Reverse (fl oz to tsp):
teaspoons = fl oz × 6There are exactly 6 US teaspoons in 1 US fluid ounce (fl oz). Therefore, 1 teaspoon equals exactly 1/6 fl oz (~0.1667 fl oz).
1 tablespoon is half a fluid ounce (0.5 fl oz) and equals exactly 3 teaspoons.
Fluid ounces (fl oz) measure volume. Dry ounces (oz / avoirdupois) measure weight (28.35 g). For water, 1 fl oz weighs ~1.04 dry oz.
1 standard US measuring cup = 8 fl oz = 16 tablespoons = 48 teaspoons.
One US teaspoon is equal to 1/6 of a US fluid ounce, which is approximately 0.1667 fl oz.
There are exactly 6 US teaspoons in 1 US fluid ounce (or 2 tablespoons).
There are exactly 3 teaspoons in 1/2 fluid ounce, which is also equal to 1 US tablespoon.
There are 1.5 teaspoons in 1/4 fluid ounce (0.25 fl oz).
No. Dry weight ounces measure mass (28.35 grams per oz). A teaspoon of flour weighs only ~2.6 grams (~0.09 dry ounces). Only fluid volume follows the 6 tsp = 1 fl oz rule.
