1/8 Tablespoon to Teaspoon
1/8 tbsp = 0.375 tsp
= 1.85 ml | 0.0625 fl oz | 0.0078 cups
Australia: 1/8 tbsp = 0.5 tsp (20 ml tablespoon)
One-eighth of a tablespoon is 0.375 teaspoon or 1.85 ml. This is below the threshold of typical measuring-spoon sets, which usually go down to 1/4 teaspoon (0.25 tsp). For practical purposes, the closest standard measurement is 1/4 teaspoon (= 0.5 tbsp), which gives you 33 percent more than 1/8 tablespoon. If your set includes a 1/8 teaspoon measure (less common but available in baking-specific sets), use that and add a small extra pinch. The quantity appears in tiny spice quantities (saffron, asafoetida) or in dropper-measured liquid extracts. In Australia, 1/8 of a 20 ml tablespoon is 2.5 ml (= 1/2 metric teaspoon).
