1 TSP to Oz – Answer with Formula

1 teaspoon (tsp) is equal to 0.1667 ounces (oz).

The teaspoon is a smaller unit of volume commonly used in cooking, while ounces can measure both weight and volume depending on context. Here, we convert 1 tsp, a volume measure, to fluid ounces (oz), using the standard conversion where 1 tsp equals approximately one-sixth of an ounce.

Conversion Formula

The formula to convert teaspoons (tsp) to ounces (oz) is based on the fact that 1 teaspoon is one-sixth of a fluid ounce. So, to convert tsp to oz, multiply the number of teaspoons by 1/6 or approximately 0.1667.

Mathematically:
oz = tsp × (1 ÷ 6)
For example, for 1 tsp:
oz = 1 × 0.1667 = 0.1667 oz.

This works because the US customary cooking measurements define 1 fluid ounce as 6 teaspoons, so dividing the tsp value by 6 gives the equivalent in ounces.

Conversion Example

• Convert 3 tsp to oz:
  – Start with 3 tsp.
  – Multiply by 0.1667: 3 × 0.1667 = 0.5001 oz.
  – So, 3 tsp equals approximately 0.5 oz.
• Convert 7 tsp to oz:
  – Take 7 tsp.
  – Multiply 7 × 0.1667 = 1.1669 oz.
  – Result: 7 tsp equals about 1.167 oz.
• Convert 0.5 tsp to oz:
  – Half a teaspoon is 0.5 tsp.
  – 0.5 × 0.1667 = 0.08335 oz.
  – So, 0.5 tsp is roughly 0.083 oz.
• Convert 12 tsp to oz:
  – 12 tsp multiplied by 0.1667.
  – 12 × 0.1667 = 2.0004 oz.
  – Therefore, 12 tsp equals about 2 oz.
