Teaspoons to Fluid ounces Converter
Converting teaspoons to fluid ounces is a multiplication by a fixed factor: 1 tsp = 0.1666667 fl oz. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one teaspoon works out to 0.1666667 fl oz, the fluid ounce is the much smaller unit of the two: a figure given in fluid ounce always carries a smaller number than the same measurement in teaspoon. A chart drawn in tsp can hide that, so check which label the axis uses before you compare two readings.
Kitchen and workshop measuring are where this pair comes up: a jug marked in teaspoons alongside a recipe or container printed in fluid ounces is the classic case, and it is why the two labels rarely agree to the eye.
The conversion factor used here is 0.1666667 fl oz per teaspoon (7 significant digits as shown). Kept to seven figures it covers professional measurement; if you round it to two or three decimals for a spreadsheet, the error scales with the input — at a value of 1,000 tsp a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 6 tsp per fl oz, the exact reciprocal, so a round trip through both pages returns your original number.
