Estimating in your head

Divide by 3 for a quick figure; it is off by about 0%. For 6 tsp that gives 2 tbsp, against 2 exactly.

tbsp = tsp × 0.3333333333

1 tsp = 0.00000492892159375 m³ and 1 tbsp = ≈ 0.00001478676478 m³, both by definition, so the factor is their ratio: 0.3333333333 (rounded here; the page uses the full value). Results drop binary floating-point noise beyond 15 significant digits and display at the precision you choose (6 significant figures by default). Copy result copies the full value.
