Formula
To execute this calculation, the value in Teaspoon (US) is first normalized to the base Volume unit (Liter) before being scaled to Cup (US). The direct multiplier for Teaspoon (US) to Cup (US) is determined by the ratio of their scientific definitions.
Examples
For instance, 1 tsp is strictly defined as roughly 0.020833347422523543 cup. If you are dealing with a larger scale, such as 50 tsp, the resulting cup value maintains this exact linear proportionality.
Reverse Formula
The inverse conversion (Cup (US) back to Teaspoon (US)) is equally valid and uses the reciprocal of the primary ratio. Our interface allows you to toggle this direction instantly to verify both sides of the Volume equation.
Common Mistakes
The most frequent error in tsp to cup calculations is the misapplication of unit prefixes (like centi- or milli-). Additionally, confusing Teaspoon (US) with similar units in different systems (like US vs. Imperial) can lead to significant discrepancies.
