Tablespoons to Teaspoons Converter
Converting tablespoons to teaspoons is a multiplication by a fixed factor: 1 tbsp = 3 tsp. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one tablespoon works out to 3 tsp, the teaspoon is the larger unit of the two: a figure given in teaspoon always carries a larger number than the same measurement in tablespoon. A chart drawn in tbsp 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 tablespoons alongside a recipe or container printed in teaspoons is the classic case, and it is why the two labels rarely agree to the eye.
The conversion factor used here is 3 tsp per tablespoon (0 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 tbsp a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.3333333 tbsp per tsp, the exact reciprocal, so a round trip through both pages returns your original number.
