Conversion Formula
The basic formula to convert teaspoons (tsp) to fluid ounces (oz) is:
oz = tsp ÷ 6
This works because there are exactly 6 teaspoons in 1 fluid ounce. Since a teaspoon is smaller, you divide the number of teaspoons by 6 to get the equivalent fluid ounces. The formula comes from standard volume measurements used in cooking and liquid measurements.
Example: converting 1 tsp to oz:
- Start with 1 teaspoon
- Divide by 6 (because 6 tsp = 1 oz)
- 1 tsp ÷ 6 = 0.1667 oz
Conversion Example
- Convert 3 teaspoons to ounces
- Take 3 tsp
- Divide by 6: 3 ÷ 6 = 0.5 oz
- So, 3 teaspoons equals 0.5 ounces
- Convert 12 teaspoons to ounces
- Start with 12 tsp
- Divide 12 by 6: 12 ÷ 6 = 2 oz
- Result is 2 ounces
- Convert 0.5 teaspoons to ounces
- Use 0.5 tsp
- Divide by 6: 0.5 ÷ 6 ≈ 0.0833 oz
- Half teaspoon is about 0.0833 ounces
- Convert 9 teaspoons to ounces
- 9 tsp divided by 6
- 9 ÷ 6 = 1.5 oz
- So, 9 teaspoons equals one and a half ounces
