Australia: 1.33 tbsp = 5.33 tsp (20 ml tablespoon)

1.33 tablespoons is the two-decimal way recipe scalers and nutrition apps write 1 and 1/3 tablespoons, and it equals exactly 4 teaspoons (19.7 ml). A calculator that multiplies the rounded 1.33 by 3 returns 3.99 teaspoons, but that is a rounding artefact: the true value is 4/3 tablespoons, and 4/3 x 3 = 4 teaspoons on the nose. Measure it as 1 tablespoon plus 1 teaspoon, or simply 4 level teaspoons. The quantity appears when a recipe originally built on 4 teaspoons of a spice, leavener, or extract is displayed back in tablespoons by a scaling tool. In Australia, where the tablespoon is 20 ml (4 teaspoons), 1 1/3 AU tablespoons is 5.33 teaspoons. Going the other way, see 4 teaspoons to tablespoons.

Common Questions

What is 1.33 tablespoons in teaspoons?
1.33 tablespoons equals exactly 4 teaspoons. The 1.33 is a rounded decimal for 1 and 1/3 tablespoons (4/3 tbsp); the exact fraction times 3 is 4 teaspoons, not the 3.99 a calculator shows when it multiplies the rounded 1.33.

Because 1.33 is a two-decimal rounding of 1.3333... (one and one-third). The exact value is 4/3 tablespoons, and 4/3 x 3 = 4 teaspoons exactly. The 3.99 result appears only when 1 1/3 is rounded down to 1.33 before multiplying.
