How the conversion works

The relationship is cup = tsp × 1/48. Both units measure volume, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.

US cup: US legal cup is 240 mL; the customary cup used here is 236.588 mL.
