Australia: 0.4 tbsp = 1.6 tsp (20 ml tablespoon)

Four-tenths of a tablespoon is 1.2 teaspoons or 5.9 ml. This is just over one teaspoon (1 tsp = 5 ml). Practically you would measure 1 teaspoon plus a small pinch (about 1/8 teaspoon = 0.125 tsp would put you at 1.125 tsp, close enough). Decimal-tablespoon quantities like 0.4 typically come from recipes scaled from a 5x or 10x batch where ingredients were normalised to decimals. In Australia, 0.4 of a 20 ml tablespoon is 1.6 metric teaspoons (8 ml).
