Australia: 0.1 tbsp = 0.4 tsp (20 ml tablespoon)

One-tenth of a tablespoon is 0.3 teaspoon or 1.5 ml. This is a trace amount, smaller than a fifth of a teaspoon. It comes up in concentrated-flavour calls like a single drop of food colouring or the smallest practical pinch of cayenne in a one-cup sauce. To measure it precisely, fill a 1/4 teaspoon to slightly more than the halfway mark, or use a pipette for liquid extracts. The US/UK ratio is the same exact 3:1 (tsp per tbsp); in Australia 0.1 of a 20 ml tablespoon would be 0.4 metric teaspoons (2 ml).

Common Questions

What is 0.1 tablespoon in teaspoons?
0.1 tablespoon equals 0.3 teaspoon. The math: tbsp x 3 = tsp, so 0.1 x 3 = 0.3 tsp.
How do I measure 0.1 tablespoon?
0.1 tablespoon is 0.3 teaspoon (about 1.5 ml). The most practical method is to fill a 1/4 teaspoon to roughly half-full, or use a calibrated dropper/pipette for liquid extracts. Most home kitchens cannot measure this precisely without a 1/8 teaspoon or 1/16 teaspoon measuring spoon.
What is 0.1 tablespoon in ml?
0.1 US tablespoon equals 1.5 ml using the NIST 14.79 ml/tbsp standard. 0.1 UK tablespoon is exactly 1.5 ml (UK tbsp is 15 ml exact). 0.1 Australian tablespoon (20 ml AS 1291) is 2 ml.
When would a recipe use 0.1 tablespoon?
Decimal-tablespoon quantities like 0.1 typically appear in scaled-down recipes from a 10-serving batch, or in nutrition calculators where ingredient quantities are normalised to grams and converted back to volume. For most home cooking, 0.1 tablespoon rounds practically to a small pinch.
