1.3 Tablespoons to Teaspoons

1.3 tbsp = 3.9 tsp

= 19.2 ml  |  0.65 fl oz  |  0.0813 cups

Closest practical measure: 4 tsp (a little less)

Australia: 1.3 tbsp = 5.2 tsp (20 ml tablespoon)

One and three-tenths of a tablespoon is 3.9 teaspoons or 19.2 ml. It is a value you usually meet after scaling a recipe up or down, or reading it back from a nutrition tracker, rather than one a recipe writes out on purpose. In practice it sits a hair under 4 teaspoons, which is 1 tablespoon plus 1 teaspoon: measure 1 level tablespoon and 1 level teaspoon and you land within about 2 percent, close enough for anything that is not precise baking chemistry. Do not confuse it with 1.33 tablespoons (1 and 1/3 tbsp), which is a shade larger and works out to exactly 4 teaspoons. In Australia, where the tablespoon is 20 ml, 1.3 tablespoons is 26 ml or 5.2 teaspoons.
