About this conversion
This page converts teaspoons per day (tsp/d) into cubic inches per fortnight (in3/fn), two units of volumetric flow rate.
The Teaspoon (tsp) is a unit of volume. The Day (d) is a unit of time.
The Cubic Inch (in3) is a unit of volume. The Fortnight (fn) is a unit of time.
The formula is in3/fn = tsp/d × 4.21094, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
